Describe the bug
The OpenDyslexic Mono font, despite being a monospaced font, cannot be installed such that the operating system actually views the font as monospaced

To Reproduce
Steps to reproduce the behavior:

1. Launch a program that only allows monospaced fonts (i.e. Windows Terminal or iSH)
2. Go to the program’s font settings
3. Open the menu to change the font
4. Notice that OpenDyslexic Mono is not on the list

Expected behavior
I expected OpenDyslexic Mono to be recognized by the system as a monospaced font, and thus be freely available to use in programs that required them.

I’d put a nice video here, but Github on Firefox for iOs wouldn’t let me :(

Describe the bug
The Š and š letters are displayed as the exact same "glyph", if that's the correct word for it. First line is in Liberation Sans, second has the exact same content, just is in OpenDyslexic. I'm sure you can see the problem:

However I didn't notice anything out of ordinary with any other letters, which is really nice:

To Reproduce
Steps to reproduce the behavior:

1. Try to display š in any way. It's just the wrong size.

Expected behavior
I would expect š to be sized as a regular s, only with the mark above it. Not Š.

The first seen text on the website is white text over the image of big black letters. The letters in the image in the background has higher saliency than the text. Readability of the introduction text could be improved e.g. by (re-)moving the image or reducing it's contrast significantly.

Sorry this is not a feature request but question about the license.

I am building an Open Source (MIT) application which is a templating system which generates PDF files. A user answers a set of questions and in turn a PDF is generated to match their specification. The application has multiple interfaces. It can be used via CLI, API and a web app.

I am very keen to allow people to chose opendyslexic as the font to be used in their generated PDFs. To do this I would use the font in the backend service, which would bundle the font as part of the PDF. A user of my software may never download anything other than a PDF.

My questions about how the license will impact my work are:

• Am I required to give attributions to the font?
• If I am required, where am I required to give the attribution? In every PDF? In my Github README? In my web interface?
• Am I required to include a copy of the license?
• Can I distribute my software under any license?
• Can I distribute my software for profit (not currently my plan but just want to cover my bases)

I have read both the OFL.txt file and the OFL-FAQ.txt file in depth. However, I was unable to answer my questions based on these documents, mainly because I don't understand the legal wording.

I tried to give a little money for the download on the https://antijingoist.gumroad.com/l/OpenDyslexic page - but it would not accept any of my cards - even those I use fine everywhere else. I had to put 0 in to get to the download. I just wanted to let you know you might need to check that it's working.

Although the onum, tnum, pnum and lnum features are advertised by the fonts, the actual figures are just tabular lining.

Opendyslexic shifts texts to the far past the margins making the text unreadable.

Describe the bug
At some point very recently the Chrome Webstore reported the extension as unsafe or malicious and removed it. This has also caused Edge to remove the extension because of the unsafe flag in the Chrome Webstore. The URL for the store page now results in a 404

As I get older I am having more problems with my vision and have found the OpenDyslexic font really helps me. However, I've recently been asked to do a lot of stuff in Google Sheets, Docs, and Forms. I've tried adding OpenDyslexic to their fonts list, but can't find a way to do it. I've asked for help from several places, and none of them know how to do it. I even tried asking Chrome and Google to help, but all they did was suggest I contact you about adding your font to their service. I don't know if that means you have to create an add-on or what, but it would be really helpful to have access to OpenDyslexic in the apps I need to use.

Why?

I'd love to use that awesome font with all my IDEs (Xcode, IntelliJ IDEA, Goland), text editors (mostly SubEthaEdit) and of course the Terminal.app

Since code highlighting in those applications use different font types to somewhat distinguish the purpose (simple comment vs. rich Markdown documentation, common console output vs. debugger output) it would be awesome to simply exchange, say "SF Mono Bold" with "OpenDyslexic Mono Bold".

What?

I tried different colors, which does not work that good for me.
Also simply using another OpenDyslexic font for those type of information did not work well, since I got used to monospaced fonts

Currently the only way to use OpenDyslexic is by using the provided assets. Providing instruction on how to build it from source would allow modification and building to any format (ie. TTF is currently missing).

PS: I don't think you should bundle the compiled files into git but only into release archives, as git should be used for sources and mostly text files.

Hi!

First of all, great job!

I read somewhere that you might add additional letters on demand.

Is it possible that you add the following letters?

Ğ (uppercase)
ğ (lowercase)
İ (uppercase)
Ö (uppercase)
Ü (uppercase)

Your work is really appreciated...

I had a bit of a hard time trying to decide how to raise this question, so if there's a more appropriate option please forgive me and do tell me the proper way to discuss this. Also, though some may consider this a bug (I also would some time ago) since it's "missing documentation", I opted to post as a Feature Request since it only impacts choice of font version, not it's usability.

Going straight to the point: A choice is offered with zero data about pros and cons or trade-offs to be considered. I believe this could be easily amending by claridying: Is there any data on the impact of having a rounded "a" versus the regular "a"? What does it say? This is even more relevant in the off-chance that such data clearly evidences either option being superior to the other in any situation.

If there's no difference, or if there's not enough data about it, this information should be available, and if there are differences, those should be publicly available, and preferrably easy to find when the decision on using either or even both needs to be made (i.e. download page).

I'm not questioning the existence of an alternative, the more the merrier, and it's quite easy to see the relevance for designers. My issue is with there being absolutely zero information on pros and cons, trade-offs or whatever of either version. It can be pretty frustrating in a situation when either option is equally acceptable, even more so if the one making the decision doesn't have Dyslexia (but wants to maximize readability). Obviously it's equally important to mention data on differences between individuals or the lack of such data (i.e., children could find the rounded a easier while adults think it's harder or see no difference).

From an engineering standpoint, even a simple sentence stating that there's no data on this subject would be very helpful. This may or may not be common sense to dyslexic people or easy to guess for some, but a lot of people who care about dyslexic readers may be losing quite a bit of time trying to figure this out, especially non-dyslexic ones. In my case I spent quite a bit of time searching on both repos, plus the website, plus Google. And depending on the replies here (And how much time I'm able to spend on this) I may even decide to read articles on the matter since it picked my interest.

This could be easily fixed by adding some pointers, making adoption of OpenDyslexic easier and more straightforward. I think I've covered pretty much everything relevant and also how this is directly related to the purpose of OpenDyslexic, as in how much each version actually helps dyslexic people. Please do share any pointers and/or feedback you may have.

@antijingoist am I missing something?

I'm a huge fan and as we deal with complex documents and legal contracts being able to provide people with easier to read material is a huge bonus. Thank you for doing this.

One of the key findings we have had, and I have been diagnosed with, is a condition called Irlen's syndrome, which is also in the dyslexia area. Personally, I haven't had any trouble with reading, but many do as a result of this condition and in conjunction with the use fo your font, could be a life-changer for many.

Where the words on the page are fuzzy, shimmering, moving, shadowed, or highlighted with a 3D effect, there's a good chance that Irlen syndrome has a part to play. With the application of an appropriate coloured filter, Irlen's can be easily solved and this reduces one of the many difficulties dyslexics have to contend with.

www . irlen . com is the best place to find out more. Also happy to discuss in more detail as we have had a number of people diagnosed with this and it has been life-changing for them to date.

Having some additional information on this in your readme would be helpful to raise the awareness of this as a thing that people can check out for themselves. Thank you!

I've noticed that the Greek fonts are not well-drawn. If I edit them in FontForge and send you the OTF, can you include them in the distribution?

Describe the bug

When typing/reading multiple backticks ` in a row, they become invisible causing problems typing markdown.

To Reproduce
Steps to reproduce the behavior:

1. Open https://guides.github.com/features/mastering-markdown/#examples with the browser extension loaded
2. Click on Code
3. Read how to type codeblocks in GitHub flavoured markdown.

I am also able to reproduce this on Pluma (MATE fork of Gedit) when I set the font as OpenDyslexicMono Regular.

Expected behavior

Backticks are clearly visible.

Screenshots

• 
  • With the extension on the third line the backticks have become accented characters. This looks like OpenDyslexic/extension#33.
  • The multi-line codeblocks called as fencing are all merged to one.
• 
  • Without the extension backticks and fenced codeblocks come visible.

Hi,
In the ReadMe you have bundled with the download zip file, you have instruction on how to install on Windows and Mac. Here are the instruction on how to install on a Linux machine:

"Linux: Copy .OTF files to ~/.local/share/fonts "

I thought that you could add this to your ReadMe.

Like Windows, there are also font installers on the OS (on many Linux distributions), but as you just have the copy-paste instructions for Windows, I thought you would only want that for Linux too.

Added extra information:

Have the fonts available system-wide, not just that user:

Copy the .OTF files to /usr/local/share/fonts

My mother has macular and reads a Kindle. Open-dyslexic is her favorite font. The problem is she's on the largest font her Kindle will display, and her vision is getting worse.

If there were a way to make versions the font larger at their base so the would display larger on the screen at the same font size, that would be ideal. I'm thinking maybe scaled 110, 120, and 130% if possible.

This may violate some official spec for fonts, but it's a hack that could work, and that's more important. If the added height cramps the line spacing, that won't be a problem because we can adjust the line spacing on the Kindle.

I expect my mother is only one of many who would benefit from this. Something like this on a different font for the original Kindles, and people liked it, but those files don't work on modern Kindles, nor do they use this font.

Thank you for any help you can be on this.

Hey there, just a small improvement proposal:
Having a screenshot with some text laid out would be aweseome! :)

Thanks for considering.

Use-case:

Many websites and web solutions have integration with Google Fonts and it would expose OpenDyslexic to the masses.

Background:

I'm running a MKDocs Material Wiki site:
https://retrodeck.readthedocs.io/en/latest/

Then I had the idea of a toggle that could switch the active session over to OpenDyslexic font with the click of a button.

So I created an issue to look into it:
XargonWan/RetroDECK#613

Then I started a discussion over at the MKDocs Material Github:
squidfunk/mkdocs-material#6512

After some debate over at MKDocs Material the suggestion was to ask you to consider submitting the font to Google Fonts... and now I'm here!

Currently OpenDyslexic does not support all diacritics used in the ISO 15919 standard.

Characters missing that I found: (might not be complete)
ǣ ẖ ḫ h̤ ḵ k͟h l̥ l̥̄ ḻ m̐ ṃ m̆b n̆ ṉ ñ r̥ r̥̄ ṟ r̆ ṣ s̱ s̤ ĉ t̤ ẏ ẕ

The addition of a few characters would make the font compliant with ISO 15919.
A list of diacritics can be found on wikipedia

Thank you very much!, I hope someone will be able to add these characters and make the font even better!

Hi,
I'm porting this for OpenBSD. Currently (0.9.10 beta), when fetching from the release .zip provided, only the compiled fonts, pdf and a bin folder are included.

This means that the license/documentation does not actually come distributed with the release we would be fetching. Our project prefers to use a static zip where possible, but I can only comply with the license by bypassing the .zip and using the source tree at the same point. Is this just an oversight? (edit: also, is it meant not to have a directory structure?) I can work around it with the tagged tree, or we can wait for a release that adds those in as well.

Thanks for your work, and for making this available for distribution!

** Notes
Yes, I can install other fonts like Segoe UI from Microsoft and it works.

It does nothing with OpenDyslexic fonts... Please help. Can't install (does nothing, it seems to install but does not show, no warnings, no errors), can't use it. Yes I did reboot the machine.

Yes it did worked on an other macOS on the same machine. Everything worked just fine. Can't remember which version it was.

The U+2236 (∶) character is missing which leads to an unknown symbol being shown when using this as the default font for windows.

Are you able to create a OneUI font on the Samsung store? Would like to use this font system wide.

Keep the "b" as it is, please! It is perfect!!! :-)
It is so rare to find "b" that look like the way we now teach children to write them: after going down to trace the stem, we immediately go right to draw the counter, like in cursive writing.

Characters to modify to make it look more like students learn them:

• a (like "q" without the descender)
• y (like "u" with a curly descender like "j" or "g")
• J (with a bar like "T")
• 9 (like a large "q" standing on the baseline)

Note: I speak for Quebec schools, I cannot say if the needs are the same for other countries!

Hi,

Firstly, I really love this font & I appreciate all the work that's gone into it!

As a regular TeX user who writes mainly scientific/mathematical documents, I would love to see more commonly used mathematical glyphs (e.g. contour integrals, dots over letters to represent time derivatives, things like \lesssim for us astronomers) incorporated into OpenDyslexic.

The current math mode typeface in LaTeX (Computer Modern or Latin Modern) is extremely difficult for some, given its serifs, nearly uniform letter shaping, etc. Integrating these features would be incredibly useful for the presumably large community of people in STEM professions who struggle with dyslexia!

I'm aware that some basic glyphs have already been developed (e.g., integrals, I think both total & partial derivatives, the Greek alphabet) so I believe the stylistic foundation for mathematical glyphs is already in place.

I have no experience in designing or coding fonts, but I'm happy to volunteer to contribute if I can be of any help!

Thanks,

Luca (he/him/his)

Describe the bug
I was just doing some testing with using this font on a game I'm developing and noticed some missing glyphs. I don't see an existing issue for missing Unicode glyphs so I figured I'll start a new one. I noticed in the game that the following glyphs seem to be missing:

• Ellipse (…)
• Non-breaking space ( )

So I did some checking on dafont.com (I couldn't find a better convenient way to check what glyphs are and aren't available) and saw that at least the version of the font they have is also missing the following glyphs:

• En dash (–)
• Em dash (—)

I noticed that some others are missing as well (like the arrow symbols and music symbols), but I figured I'd specifically note the ones above since they are necessary components of proper English text (and probably text of other languages as well).

I downloaded this font to help with my issues and being a developer and come to find out its loaded with trojans.

I requested Wikimedia to install OpenDyslexic (for svg-rendering): https://phabricator.wikimedia.org/T285650

The Bugmaster pointed to another bug: Update OpenDyslexic when it has a new stable release

If I check https://github.com/antijingoist/opendyslexic/releases I can only see Pre-release, but no stable release.

The naming of versions such as nighty, development, alpha, beta, testing, release-candidate is imho very different between projects.

(When) Do you plan to make a stable release, whatever it means for you? (I know time/money is limited for everyone.)

Describe the bug
Using the fonts from this repo, I am unable to change color via a color: CSS rule when using on a webpage. The font color is always black. This is the case whether I use the .woff or .woff2 files from this repo with @font-face, or the .otf installed locally.

To Reproduce

@font-face {
    font-family: "OpenDyslexic";
    src: url("/assets/fonts/OpenDyslexic-Regular.woff2") format("woff2"),
      url("/assets/fonts/OpenDyslexic-Regular.woff") format("woff");
}

* {
    font-family: "OpenDyslexic", sans-serif;
   color: #fff; /* should be white but is black */
}

Expected behavior
Expected to be able to change font color.

On opendyslexic.org the font is shown in different colors. It uses a different font file, a .ttf which is not included in this repo.

I am a middle school teacher who is extreemly dyslexic. When you published the Chrome add on, you did an amazing job. Thank you for making my life SO much easier!

I am wondering if there is a way to apply the OpenDyslexic font to PDFs and Google Docs, sheets, etc.

Thanks!

I have pinned + mirrored the files to https://opendyslexic.ftcg.org/

When viewing the font on a white background on an average consumer grade device, the top of the characters seem to prematurely fade into the background color. On the opposite side of the spectrum, if using a black background, the premature fading is not apparent and the characters are very clear and distinct; no premature fading on either the top or the bottom of the character.

• I have not seeing the same behavior when opendyslexic is substituted to another font(light fonts bolded or naturally dense fonts).

• ClearText does not seem change the font rendering either way.

• I mainly attempt to use opendyslexic as the default font for web browsing, so there could be a chromium contribution.

• I do not see the same behavior when viewing images of the rendered font in the examples font images shown on various pages (unclear if font version and size are the same ).

I understand that is not an issue with "the font" and is for the most part a visual perception of the rendered font is subject to the user, the user's device and device color settings. Most consumer grade devices do not have the best control of brightness and contrast and obtaining a linear spectrum of a color from 0 to 255 is quite difficult is not impossible. The actual linear spectrum is probably more in the range starting at 10+/-5 to 245+/-5.

I do not know anything on font design, but is there any way increase color value used in the anti aliasing of the top of the character to resemble that of the anti aliasing pattern used in the middle and bottom of the character?

Hello,

In Debian we used to ship opendyslexic, including the Mono and Alta variants, but in the latest tarballs I cannot file .otf files for them in compiled/. Would it be possible to build .otf files for them? I tried to use glyphes2ufo + ufo2ft to do the conversion, but this is failing...

Samuel

It sounds like this project could benefit from using machine/deep learning/genetic solutions.

Right now from what I am reading, humans try various solutions and modify the font based on the results observed.

If one were to define various properties of the font (different features of each letter that can be set at various values), one could devise a test (either a straight up test system where people volunteer to read a given version/set of those parameters, and give a note on how well that version/set worked for them, or even a game) in which different values for those features are tested and given a notation, this data could then be used (possibly live, with adjustments/next generation testing) on the go to improve and define the next generation of parameters.

I feel like this might possibly be powerful in its ability to improve the font.

If somebody else is interested in exploring this, I'd love to give a hand and help create a proof of concept for what I'm describing here. I'd need a bit of help to figure out what parameters it would make sense to adjust/explore/optimize, but once I've been helped with that, creating the proof of concept game/test platform is something I feel I could take a crack at.

Asking this just in case somebody thinks this is interesting, sorry if this is out of the bounds of what is of interest to the project.
Sorry if this is already something you are working on, I browsed the available documentation and did not find this, but I might have missed it.

Cheers!

When using font-size-adjust, the font goes much much smaller than it should.

Here is without font-size-adjust:

And here is with font-size-adjust: 0.5:

Which definitely seems wrong.

There is a capital letter where a small letter should be
u+0161, small letter š is replaced by capital Š
