Qt5.13 cannot display Chinese on browser

[tham]

Qt version : 5.13.0, webassembly
os : ubuntu16.04

Porting a very simple Qt app to browser, it is just a QPlainTextEdit, no matter how I try, it can't show Chinese on the QPlainTextEdit on Chrome/Firefox, I have tried the textEdit example at here too.

Sounds like webassembly of Qt support do not support unicode yet?

Found the answer, webassembly do not come with system fonts, you need to load a font manually. You can use FontZip2 to save some space of your webapp
