iOS App not support Chinese

The OnlyOffice iOS App cannot display Chinese characters properly.
Also, Chinese IMEs are not supported, we cannot input Chinese into a worksheet.

BTW, I mean simplified chinese.

Hello @rayyu, the Chinese symbols input in Mobile Spreadsheet Editor is a known issue, we are working on it. As for the Chinese symbols display, please provide a file with which the issue can be reproduced

Cannot upload font file in the forum. The name of font is msyh.ttc, it’s a official chinese font from Microsoft.

Can you upload a file that uses this font and has problem with display in mobile app?
As for the font itself, it can be uploaded to some file hosting provider, the link can be shared here

msyh.ttc

here it is

Also this one
simsun.ttc

I think the compatibility of Chinese fonts is a common issue, not only for specific Chinese fonts.
