一个完整版，一个只带regular字形

For new iOS and OS X.

1. 黑体为何要加 Tahoma 且加在 Arial 前面？Tahoma 和 Arial 都是 Windows 带的字体，没必要包含两个，而 Arial 更接近 Helvetica。
2. 应该给楷体、仿宋的方案增加英文字体，常见的楷体、仿宋的英文部分惨不忍睹。

@zenozeng , thanks for your help in #33,
Do we need to fetch other files such as fonts.less, fonts.scss, fonts.styl?
or we only need to fetch fonts.css? Thanks!

cdnjs/cdnjs#9171

后两者在 OS X 上有多个字重。

Hi @zenozeng ,
I am the member of cdnjs project,
and we want to host this library,
I have some problems,
I downloaded the library from npm,
but I found that there are only two versions (v1.3.1 , v1.4.0) in npm.
However there are 5 versions in github.
Can you help me add the missing repositories (v1.0.0 , v1.1.0, v1.3.0)? Thanks!

cdnjs/cdnjs#9171

如图，官网除了黑体之外，其余中文字显示全都显示为宋体

Google Chrome 60.0.3112.90
macOS Sierra 10.12.6 (16G29)
未做任何字体相关自定义设置

But SF is still a hidden font in OS X El Capitan, we cannot specify it directly. Instead, -apple-system works. Ref: http://furbo.org/2015/07/09/i-left-my-system-fonts-in-san-francisco/

大赞这个 fonts.css

能加到 bower 就更好啦！

thanks for your great work!!!

几种默认的 font-family 回退

font-family: cursive;
font-family: fantasy;
font-family: monospace;
font-family: sans-serif;
font-family: serif;

在桌面端中英文字体都有效，在移动端英文字体都有效，但中文字体能用的只有 无衬字 (sans-serif)。

是否有除了 web-font 之外的解决方案？

The Kai family is not working properly on my Windows 10 which has Traditional Chinese support files installed only, and I believe the GB or Simplified Chinese edition of KaiTi font will be installed only if SC support was added.

So I was wondering if you could add DFKai-SB to the list. DFKai-SB(https://zh.wikipedia.org/wiki/%E6%A8%99%E6%A5%B7%E9%AB%94) is a TC version of Kaiti font and support both TC and SC.

比如 黑体（细）fallback到黑体

Since the code points of the curved quotation marks are shared by Chinese and Western scripts, according to the generated CSS, the quotation marks are displayed as Western quotation marks, because Western fonts (like Noto Sans) are put before Chinese fonts, which do not conform to the Chinese layout requirements. Dashes, ellipses, and middle dots have the same problem.

The clreq project solves this by using the unicode-range CSS descriptor: https://github.com/w3c/clreq/blob/gh-pages/local.css

版权问题不应该由前端负责，显示效果的优先级应该更高。
何况在 Mac 中华文为默认字体。
一个字体既然能被调用，对于 API 层级来说应该就认为它是可用的。

CSS uses cursive as 楷体 [1] and fangsong as 仿宋. They can probably be put before serif in the font-family as more appropriate fallbacks.

Footnotes:

[1] Although there have been discussions about changing that.

18px

Each font of Source Han Sans family has seven font weights: Extra Light, Light, Regular, Normal, Medium, Bold, Heavy. They are separated into seven fonts (seven otf or one otc), but they belong to the same font family Source Han Sans CN/TWHK/JP/KR.

If the operating system handles opentype fonts correctly, then they can be used as one single font, for example "Source Han Sans CN". When you ask for different font weight, the system will select the correct variation to render instead of using pseudo bold/light version. This is the case in Linux and Mac OSX. Windows needs to be tested.

Therefore, the correct font-family name in CSS should not have "normal" or other suffixes.

如 font hei regular 简写为 font hei

Cake 生成的 less 应该要加上 ~ 以避免错误

I am thinking about how to deal with Traditional Chinese better.

Currently the font sequence works good for SC, but not OK for TC. The most troublesome part is that some characters have the same code point in SC and TC but have different "standard" or "preferred" glyphs.

Another problem is that the popular/preferred fonts in mainland and TWHK are not the same.

Source Han Sans project works this problem around by providing two version of fonts (CN and TWHK). What should we do? Two CSS?

The phrase

The quick brown fox jumps over the lazy dog

is the original and widely-used pangram, while

a fox jumps over the lazy dog

is not.

英文在中文网页下还蛮常见的，可能需要优化一下显示吧，对各个字体的搭配，另外less重用时最好要允许定制英文fallback。

In Archlinux, I cannot find "AR PL SungtiL" but found "AR PL New Sung" (opendesktop-fonts package) which is also licensed under APL. It is also a good serif/song font. You might wish to add it before/after SungtiL.
