Is there a Chinese screen display file, or can anyone provide guidance on how to join? Thank you very much

As discussed many times, there is no Chinese support in the firmware, as there are too many glyphs to support, requires multibytes strings and so on. The memory space is limited, and the strings are bytes based.
We have a kind of special string support, bitmap fonts and stuff like that.
Japanese have Katakana, which uses a limited set of glyph, but Chinese and Russian don't, hence it's not possible to support such languages (I know some Russians are using a kind of hack to support their language in a modified version of the firmware).

I'm talking about the MCU flash, not the external flash chip.
