How to add Chinese fonts

[dinpingyu]

Hello, do you know if you can add simplified Chinese fonts

[fornellas]

@dinpingyu I'm happy to merge a PR adding new unicode blocks here. From the available fonts, I'm not sure which of them support Chinese. I know for a fact that Adobe's doesn't. You may add extra fonts here, just make sure to check their licences and update LICENSE.md . Other than that, you'll need to add some tests here, check this doc as well.

There's also a hacking guide which you may find useful.

detailed graphic tutorial

Not sure what you mean by that...

There's a lot of documentation here
https://fornellas.github.io/eglib/
Which you should refer to get started.

You'll at least, have to:

• Add the fonts here https://github.com/fornellas/eglib/tree/master/fonts (including refer at local.mk).
• Patch https://github.com/fornellas/eglib/blob/master/generate_fonts.sh to use the new fonts.
• Add tests for them here https://github.com/fornellas/eglib/tree/master/tests/fonts.
• Iterate until things work.

A word of advice: the Unicode blocks for Chinese characters is quite big, I did a quick attempt of adding them, gcc would require 3G of RAM, and the generated object files were huge. Certainly, it would not be possible to use them at STM32F4, as none would have enough Flash memory for that. You'll likely need to refactor the font interface to allow font data to be pulled from other sources (eg: a uSD card) as well.
