Hi, there is a PR open for Chinese support and it includes a prebuilt font. It works well, the only reason it's not yet merged is that I need to make some changes and I haven't taken the time! If you have an issue with it, please post there:

#215

I fixed the issue with the font_converter.py, it didn't recognize hexadecimal in ranges. Thanks for the report!
