Can't display the full Chinese characters on Mac

[杨金骉]

System: MacOSX Sierra

Pyglet: 1.2.4

Python: 3.5 64bit

The English letters seem fine. However, Chinese characters can only display with the width as English letters, so the right part of a character will be masked by the next character.

How could I get the right display?

I don't know the reason, but I am sure this phenomenon would happen ^ v ^

Can you try the development version of pyglet, from Bitbucket, and see how it looks? There were some changes in the text module, but I'm bit sure if they will affect this.

If it still does not work correctly, can you provide some example code?

[杨金骉]

Hi Benjamin,

The pyglet page on Bitbucket said "Currently no development release available", so how should I do? Run  pip install --upgrade https://bitbucket.org/pyglet/pyglet/get/tip.zip ?

Hi Jin-Biao,

Actually, development is happening in the default branch on Bitbucket. Your "pip install" example should work. Or, you can just clone/download the repo, and copy the pyglet folder into your project.

By the way, which font are you using?

I had copied "simhei.ttf", which is a Chinese font named "黑体", in the working path of my code, and I called it by "pyglet.font.add_file('simhei.ttf')" and "pyglet.text.Label(‘XXX’, font_name=‘simhei’)".

However, above all are unnecessary, because I found the root of my issue...

The "simhei.ttf" is copied from my Windows' font. Although it's official, it cannot work under MacOSX. Once I replace Simhei with other TTF fonts, the displaying effect seems perfect.

And perhaps the default font of MacOSX cannot display Chinese well in Pyglet, because I used "font_name=‘xxx’" in pyglet.text.Label, but the strange displaying remained.

BTW, https://bitbucket.org/pyglet/pyglet/get/tip.zip may not fit the pyglet on python3, since I got "No module named 'future'".

Thanks for the information. I'm glad that you found a solution.

I don't know enough about fonts to say where the problem is. Maybe the fonts do not provide correct information to be rendered properly, or pyglet needs to be improved to handle non-ascii fonts better.

Do you mind sharing your not-working font? I'd like to try it on my Linux machine.

[杨金骉]

Hi, attached is that font. You can try the string "test 测试" on it.​

 simhei.ttf

I tried it on my Linux machine, and it does not work either. The unicode characters are blank (the empty box symbol, like you see when there is no valid character).

I also noticed that many of my system fonts have the same issue with pyglet. I think we can confirm that pyglet needs some improvement in this area. I wonder what the difference between working, and non-working fonts is?

Anyway, thanks for sharing your font.

Here is one of the working fonts (on Mac and Win). It's name is "Li Xuke", and it's not a common font, and I downloaded it just for testing. Hope you can find the differences!

btw, I found the Chinese Characters were unsupported in the "fontname" of "pyglet.text.Label", I got:

  File "D:\Anaconda3\lib\site-packages\pyglet\compat.py", line 75, in asbytes
    return bytes(ord(c) for c in s)
ValueError: bytes must be in range(0, 256)

Great! This should be enough data to find a solution.

Thanks!
