The Problem

The current readme recommends creating/modifying the user's fontconfig fonts.conf to make Emoji One Color the primary fallback font for sans-serif, serif and, monospace font families. This causes a number of issues including #1, #5, and #16. Ideally the DejaVu font family would stay the default and Emoji One Color would override/replace the emoji included in DejaVu Sans.

According to my tests in #16 (comment), only DejaVu Sans has the actual emoji characters which cause this problem:
which is what happens when the recommended fonts.conf is not installed.

A nice solution would be to blacklist the DejaVu Sans glyphs...

Blacklisting glyphs

There has been a number of requests for an option to "blacklist glyphs" or "create virtual fonts" in fontconfig over the years, but there is no current implementation AFAIK. (Too much detail follows, but this is a good place to keep the research.) 😉

Mixing arbitrary unicode ranges into a virtual font
might be needed when some fonts have just a few bad
characters [eg numbers], but normally mixing would be
by language.

Ideas on how to approach it [if not done already]?

src: https://lists.freedesktop.org/archives/fontconfig/2004-October/001045.html

Blacklisting glyphs in fonts has been a long standing wish for lots of
people, and the patch for fontconfig was even written once I think, but
it was never applied. Fontconfig people are just blaming the fonts with
all the different scripts. But as said before, it'll have to be
fontconfig which needs to be patched, since fonts won't do anything as
long as font substitution isn't available everywhere (and even then it
remains to be seen).

src: https://sourceforge.net/p/dejavu/mailman/message/9671050/

I remember that once upon a time the whole issue of making it possible
for FontConfig to blacklist glyphs from
fonts was discussed.

The idea was that it is easy and fast to write a few lines of XML into
a FontConfig .conf file while it is slow and
laborious to remove glyphs from a font.

Perhaps now is the time to actually implement this functionality in FontConfig?

src: https://lists.freedesktop.org/archives/fontconfig/2008-January/002847.html
Followed up by:

Sure, Pango totally uses fontconfig to determine if a font supports a
character. So this can completely be fixed in fontconfig. Someone
needs to go finish the patch and pass it through Keith I think.

src: https://lists.freedesktop.org/archives/fontconfig/2008-January/002850.html

• Finish patch for fontconfig to allow configuration to disable
  certain Unicode codepoints per font. The write such configuration for
  the crappy glyphs.

Pick whichever you prefer and just do it.

src: https://mail.gnome.org/archives/gtk-i18n-list/2007-December/msg00007.html

Solutions

As much fun as it would be to go down another rabbit hole, I don't have the time to patch fontconfig right now. Plus, backwards compatibility would still be an issue. The recommended solution is to remove the offending glyphs.

Actually IMO if the Latin glyph are crappy, removing them is the single
most correct solution.

src: https://lists.freedesktop.org/archives/fontconfig/2008-January/002846.html

This means a fork of DejaVu Sans is probably the answer. Any other ideas?! 😎

One can specify a font they want for MPV's media player in MPV's config file ($XDG_CONFIG_HOME/mpv/mpv.conf) with the "osd-font=" parameter.

Be it without specifying a custom font or using one, the digits rendering in MPV is broken:

http://i.imgur.com/946j8lQ.jpg

It works as intended when deleting the Emoji One font. I do not recall such a problem with the v1.0.0beta pre-releases.

~/.fonts/ is deprecated. The new correct location is ~/.local/share/fonts/.

XDG Details: https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html

#3. Create a XDG user font directory, if you don't have one:
mkdir -p ~/.local/share/fonts/
#4. Move the font into ~/.fonts/
mv EmojiOneColor-SVGinOT.ttf ~/.local/share/fonts/

I need to do further tests to make sure it works in all supported Linux distributions, before making any changes to the recommended install.

Homebrew is a package manager for OS X. This tool allows users to issue commands like brew cask install font-hack to quickly install a package.

@0xadada Any interest in making a package for this project also? This already has the SVGinOT-OSX font version.

I'd absolutely love it if you could make a version that used Google's Noto Emoji font.
Pretty please 🙇 🙇

If I use an Emojione supplied character in a GTK app then spaces to either side of it show up as a rectangle with four small rectangles in.

Example:

Text in the bottom is ❣ a b c ✄. Hexdump of that is:

00000000  20 20 20 e2 9d a3 20 20  20 61 20 62 20 63 20 e2  |   ...   a b c .|
00000010  9c 84 20 0a                                       |.. .|

Firefox renders those characters fine.

Steps to reproduce:

1. Install Emojione according to instructions in README
2. Type "space space space" followed by an emoji (e.g. "+:+)" for a smiley face in default Gnome ibus setup)

Behaviour: Spaces suddenly turn into boxes as soon as emoji is there

Expected: Spaces stay looking like spaces!

System: Gnome 3.16, GTK 3.16, openSUSE Leap 42.1

The packages uncompress to the current directory. Instead the files should be in a directory of the same name as the zip file and include the readme and license files.

Before

After

Firefox fonts changes take effect immediately after install. Conky happens after logging out and logging back in. I am running Ubuntu 14.04 with Cinnamon 2.8.6.

Currently, the install script overrides the file $HOME/.config/fontconfig/fonts.conf (after creating a backup). This might break other customisations of font configuration that a user did before. But fontconfig also supports a more modern approach of independent configuration files. So instead of overriding fonts.conf, I would suggest adding a file 10-emojione.conf to $HOME/.config/fontconfig/conf.d/.

I made a RPM packaging use openSUSE Build Service. Supports openSUSE, Fedora, RHEL, CentOS, ScientificLinux and SLE.

http://software.opensuse.org/download.html?project=home%3Aguoyunhebrave&package=emojione-color-font

The Fontconfig Edit Mode: prepend_first is, probably, causing a number of font selection issues #35, #37, and #39. The existing/provided configuration is technically correct according to all tests I've tried, but it is still causing problems in programs which parse the fontconfig themselves. Issue: prepend_first does not work as expected in fontconfig.

Actual 56-emojione-color.conf

  <match target="pattern">
    <!-- If the requested font is sans-serif -->
    <test qual="any" name="family">
        <string>sans-serif</string>
    </test>
    <!-- Make Bitstream Vera Sans the first result -->
    <edit name="family" mode="prepend_first"> 
      <string>Bitstream Vera Sans</string>
    </edit>
    <!-- Followed by EmojiOne Color -->
    <edit name="family" mode="prepend_first">     <!-- THIS! -->
      <string>EmojiOne Color</string>
    </edit>
  </match>

Actual Result:

$ fc-match -s sans
Vera.ttf: "Bitstream Vera Sans" "Roman"
EmojiOneColor-SVGinOT.ttf: "EmojiOne Color" "Regular"
DejaVuSans.ttf: "DejaVu Sans" "Book"

Expected, Result:

$ fc-match -s sans
EmojiOneColor-SVGinOT.ttf: "EmojiOne Color" "Regular"
Vera.ttf: "Bitstream Vera Sans" "Roman"
DejaVuSans.ttf: "DejaVu Sans" "Book"

Why the "Expected Result"? prepend_first seems like it would be applied in order, so the first font listed would become the second font in the list when a second prepend_first is encountered. It doesn't work that way though. The first font stays the first font.

Need to find a configuration that works for everything.

Font version: v1.1
Screenshots: Wrong icons: https://i.imgur.com/Lsuze7E.png

Expected display: https://i.imgur.com/cMVT4f1.png

Operating system: Linux Mint 17.3
Steps to reproduce Install Font v1.1, start the Steam client on Linux and go to the main shop site.

Since the update to font version 1.1 (Installed via PPA), the Steam client shows number icons instead of numbers on some price tags. The Steam client uses Chromium as Browser Backend.

I installed fonts-emojione-svginot (1.2-1) and fontconfig (2.11.94-0ubuntu1) from the eosrei/fonts PPA onto an Ubuntu 16.04 system.

When I visit http://eosrei.github.io/emojione-color-font/full-demo.html with Firefox 47.0, all of the emoji are displayed correctly. They are always shown correctly inside web pages. The Ubuntu window titlebar also renders all emoji correctly including regional indicators and face+color combos as a single glyph (albeit in black and white)

However the rest of the Firefox GUI is inconsistent. For the tab title, address bar, search bar, history and other GUI, most of the emoji appear in black and white, and country flags are shown as two regional indicator characters. Faces with skin colour joiners are shown as two glyphs. The only exception are 'New in Unicode 9.0' emojis which are rendered correctly and in colour everywhere. Presumably because no other installed font supports those glyphs.

I tried setting my Firefox default sans-serif font to EmojiOne but it didn't change anything. Any idea how to get Firefox to use the right font?

Firstly, thank you for this colour font - it works wonderfully in Firefox on Ubuntu.

The only issue is that the text on tabs, in the URL bar, menus, etc now uses a Serif font which looks a bit ugly.

Is there any way to keep the Emoji font, but have FF use a different fallback font for its application text?

Hope I've explained that well enough :-)

Chocolatey is a distribution tool for Windows applications, including many free software applications (for example, https://chocolatey.org/packages/pidgin). It allows an end-user to get application updates somewhat like using apt or yum on GNU/Linux.

I have not explicitly seen it used for fonts, but it basically script-based and seems like a viable platform to deliver updates, which I imagine will continue apace for a font based on Emoji One.

https://github.com/chocolatey/choco/wiki/ChocolateyFAQs
https://github.com/chocolatey/choco/wiki/Moderation

I currently have no issues with this font except for this one. I'm guessing the number emoji are overridden somewhere, but I wonder why no other emojis are. Everything else looks fine.

• Font version: 1.2
• Screenshots:
  Chrome
  
  Firefox
  
• Operating system: Arch Linux x64
• Steps to reproduce:

1. Install font
2. Open Chrome or Firefox
3. visit a page that contains number emoji

Chrome uses a serif font to display monospace text when Emoji One Color is set as the default monospace font. It should use the next monospace font.

This is the correct display when the modified config is disabled making DejaVu Sans Mono the default:

The readme currently says:

Install on Windows

The font installs like any other font and can be specifically selected, but the system will default to the Segoe UI Emoji font.

It can be manually selected in CSS, but making it the default is still TBD.

Is there a method to override Segoe UI Emoji?

Tested with 100% and 200% DPI.

When I open the font file and tap Install on Ubuntu 16.04, the install fails.

• Font version: 1.3
• Screenshots: Not necessary.
• Operating system: MacOSX
• Steps to Reproduce:

I'm currently trying to use the font from a PDF rendering library called ApacheFOP. The library does not support the non-BPM codepoints so I'm implementing the support (https://issues.apache.org/jira/browse/FOP-1969). That said I was able to print almost all the glyphs including flags (🇮🇹) and families (👨‍👩‍👦 ) using the ligatures table.

It looks like the font is missing the ligature info for the ENCLOSING KEYCAP characters (1⃣ 2⃣ etc..). I was wondering if it is a bug or an expected behavior.

Thanks

First of all, thanks a lot for these. Only issue is that when I do:

gfx.font_rendering.fontconfig.fontlist.enabled = false
restart
gfx.font_rendering.fontconfig.fontlist.enabled = true
restart
The problem with the fonts comes back

I'm using Firefox 45.0.1 on Ubuntu 15.10.
I'm just leaving it as false at the moment, not sure if it's having any detrimental affects.

Cheers

The existing b&w outlines are the default output of potrace given the current input. They are far too thin. Long term, I'd like to find a good solution to have fills, but for now the glyph weight should be increased during FontForge import.

Hello. As you probably know, when using Firefox with the current /etc/fonts/conf.d/56-emojione-color.conf, ugly things happen to the default font. In particular, even if the user has picked a specific font from the Firefox preferences, Bitstream Vera Sans will always be used.

I do not know the correct fix for this, but I have a temporary workaround. Font-config can ignore any programs that are named Firefox (or Iceweasel, for older versions of Debian GNU/Linux). Since Firefox seems to work fine without the 56-emojione-color.conf file, this is a harmless kludge.

I apologize for not providing a correct fix, but I have not yet learned the weird fonts.conf XML language. (So far, I think the FC decision to use XML to represent a programming language is rather barfy. I'd rather they just gave me a regular language and had a "compiler" to convert it to XML.)

Versions

• Firefox-ESR 45.3.0
• Debian GNU/Linux 8, Jessie
• Latest emojione-color.conf from github.

I'm attaching the debug output from running Firefox with the environment variable FC_DEBUG=1 both with and without the patch so you can see how FC is picking the fonts.

Here is what Firefox looks like when using emojione without my patch:

Applying my patch, Firefox now uses the correct font:

First of all, thank you very much for your work. I think it's awesome to be able to see color emojis at last on Linux.

I'm having a problem with Mysql Workbench, showing squares instead of text in the main screen. Most screens and dialogs also have this problem but in a minor scale, they are mostly usable.

Some details blurred on purpose, but not squares in there:

When I install emojione-color-font from AUR (using Antergos here), and my font is set to Cantarell, a serif font appears in my e-mails in Evolution. I couldn't determine any issue being closely related to this, so I opened this ticket.
I'm not even sure what additional information is required. Please let me know, and I'll update.

Using version 1.2 2160610 on Ubuntu 14.04.

I suggest removing BLACK LARGE SQUARE and possibly other monochrome glyphs from this font. Old fonts supported it fine because there's no color, but including it in the font causes some problems without any obvious benefit to me.

Problem 1: There's are some older usages of BLACK LARGE SQUARE in web apps that set the CSS color property. These all show up as black now. I understand this is a bug that they should fix and have reported it where I can.

Problem 2: On apps that fall back to the monochrome outlines, BLACK LARGE SQUARE shows up as WHITE LARGE SQUARE. For other similar symbols, the outline is harder to read than what the user previously had.

You could special case this and similar glyphs by making the fallback have a solid fill instead of just an outline, but it seems like it would be easier to just exclude it.

Other glyphs that should also be reconsidered:

🎵 🎶 〰️ ➰ ✔️ 🔃 ➕ ➖ ➗ ✖️ 💲 💱 ©️ ®️ ™️▪️◼️◾️🕐 🕑 🕒 🕓 🕔 🕕 🕖 🕗 🕘 🕙 🕚 🕛 🕜 🕝 🕞 🕟 🕠 🕡 🕢 🕣 🕤 🕥 🕦 🕧

The fonts default to emoji representation right now, which is technically incorrect. The text and emoji variation selectors should be implemented using font ligatures to correctly select text or emoji versions as requested.

The emoji style variants are all produced with the addition of U+FE0E VARIATION SELECTOR-15 (VS15) for a text presentation or U+FE0F VARIATION SELECTOR-16 (VS16) for an emoji presentation.

Details:

• http://www.unicode.org/Public/emoji/2.0/emoji-data.txt

@eosrei wrote in README.md:

[...] The font works in all operating systems, but will currently only show color emoji in Mozilla Firefox and Thunderbird. This is not a limitation of the font, but of the operating systems and applications. [...]

Why is that?

What exactly is the limitation in Linux desktop operating systems and applications?

I saw you also posted in googlefonts/noto-emoji#36.

But what exactly needs to be done to make color Emojis show up everywhere on Linux (not just in the browser)?

I'm currently packaging the font for the Arch Linux AUR, it'd be helpful if the git source provided a copy of the License section of README.md in its own file, so that can just be installed into the relevant location.

If I try the ZWJ example link from the README (http://unicode.org/emoji/charts/emoji-zwj-sequences.html) then I currently see grey shapes without any joining. Using the DOM Inspector in Firefox then I see that it is using Symbola, falling back to "Nimbus Roman No9 L".

If I edit the CSS to remove Symbola then I get joined colour images.

I thought that the fonts.conf file should have overridden all fonts to put Emoji One first, but apparently this is an exception (which is ironic, because they appear to be using a list of fonts specifically selected for their improved emoji support!)

I'm poking in to this now to see if I can work out more.

The Building section the readme needs more details about setup

https://github.com/eosrei/emojione-color-font#building

It seems to be a new security feature (rootless "System Integrity Protection") added to 10.11:

"You can't modify anything in /System, /bin, /sbin, or /usr (except /usr/local);"

Hi,

I installed the font through the ppa. Emojis work, but because the Bitstream Vera family doesn't contain any regional characters all applications that use the system default (e.g. Firefox) look like crap. :/ Uninstall fixes it (thankfully).

Can you tell me what setting/file are you changing to set the system default? I looked at install.sh, but I can't find it. (I understand Ubuntu users should be able to change the font through system settings, but I'm using Xubuntu and apparently this damn system doesn't have a GUI option for it.)

Thanks,

C.

(Also, could you maybe add a note about this to Known Issues? I bet I'm not the only non-english-xfce-user-in-need-of-emojis out there :] )

Hi,
i am on arch linux,
these fonts break the Mathematica fonts. To restore Mathematica just remove them.
hope this information helps.

Following instructions in readme.md for install on linux

As the title says.

when I do
unzip EmojiOneColor-SVGinOT.ttf.zip

I get the following error
Archive: EmojiOneColor-SVGinOT.ttf.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of EmojiOneColor-SVGinOT.ttf.zip or EmojiOneColor-SVGinOT.ttf.zip.zip, and cannot find EmojiOneColor-SVGinOT.ttf.zip.ZIP, period.

Solution was to use wget, not curl to download the zip archive.
New first line is.
wget https://github.com/eosrei/emojione-color-font/releases/download/v1.0-beta/EmojiOneColor-SVGinOT.ttf.zip

🥋 Martial Arts Uniform U+1F94B, 🥊 Boxing Glove U+1F94A, and 🥁 Drum With Drumsticks U+1F941 do not work in Firefox <47 or Character Map in Ubuntu 14.04, although they do work in Chrome.

The font itself is correct and works in OS X 10.10.

VLC assumes (reasonably) the default sans-serif system font has a full character set. The result on Linux, when Emoji One Color is the default font, is that all titles/subtitles appear as missing/error characters.

You can see for yourself. The program is KeePass.

Just a minor issue, but when I mark the squirrel/chipmunk glyph ( 🐿 ) , the black in its eye and along the tail are inverted to white.

This particular glyph seems to be quite unique in this way, as I cannot reproduce it with any of the other glyphs I've screened, so far.

Tested under Windows 8.1, with Firefox 45.

I downloaded this on ubuntu basically because I wanted a fallback font for the symbols my font didn't already support. But I don't actually like that all of my old symbols were overwritten. U+25b6 became a light arrow in a circle, for instance, instead of a nice heavy black right-facing arrow. (I'm using Chrome, so I don't get the colors)

I think that all I need to do is undo the part where Bitstream Vera Sans was made the default font, but I can't actually find where to do that. I downloaded Unity Tweak Tool, but in Fonts it says I'm using Ubuntu Regular.

On net, I'd rather uninstall everything than keep things the way they are... but ideally I could still use this font for places no other font supports.

The required color SVG transforms are currently applied as a "SVG transform" I'd prefer them "baked" into the actual SVG data to reduce potential hassles and file sizes. svgo can do this.

I thought this was a fluke earlier, but it's definitively not. The header in Firefox displays the missing glyph character in some instances. I may need to adjust the null character or add a space. Could be related to #1, but I doubt it at this point.

Windows cannot hint fonts, so: https://www.freetype.org/ttfautohint/

Hi!
I'm a Gentoo user and also maintain an overlay (non-official repo), and also maintain the package for your project.
So there are the instructions to install and to add to your README:

First install layman (if not installed) with the USE="git" enabled, with Portage. (Is enabled by default, btw)

emerge layman

Then, add my repo:

layman -s jorgicio

and then install the package:

emerge emojione-color-font

It solves dependencies.

Thanks!

Vertical alignment slightly too low, compare to selection box.

Verses DejaVu.

Some test html:

gO <a href="test.html">gO 😀 🐵 <span style="font-family: 'DejaVu Sans';">😀 🐵</span></a>

Probably something to fix in SCFBuild, hopefully it can be automated.

Need to create a PPA to install the font system-wide on Debian/Ubuntu

First of all, I would like to congratulate you on your hard work. It's great to finally see proper emojis on linux.

After installing the font, there is some overlapping text on applications such as Liferea and Geary.

System is Ubuntu 15.10, Unity 7.3.3 with Ambiance, and according to screenfetch, the (default?) font
is Ubuntu 11. It also happens on AwesomeWM running on a separate X display.

Font was installed in ~/.local/share/fonts automatically using the built in font viewer, and the config was copied from the OMG! Ubuntu! article.

Apologies if this has been reported before, I couldn't any issues related to mine while going through existing ones.
