Describe the results you received:

The thickness of the character "导" is different

Some characters are different, it used Japanese glyphs but not Chinese glyphs.(Although they are similar)

(The characters in Notepad are correct, you can find them in my source code)

Describe the results you expected:

Just like that.

I also found the same issue on Windows, but the same code works fine on Mac.

I hope this helps: page.fonts = { "SourceHan": exec_folder+"/assets/fonts/SourceHanSerifCN-Regular.otf", } page.theme.font_family = "SourceHan" text_style= ft.TextStyle( font_family="SourceHan"),

before: after:

	page.fonts = {"SHS": "SourceHanSans-normal.otf", "2": "https://www.unpkg.com/font-online/fonts/SourceHanSans/SourceHanSans-Normal.otf"}

你这 fonts 加载的写法不对吧

Yes, I also found that the support for Simplified Chinese fonts is not good enough. For example, the menu items in the picture are sometimes thick and sometimes thin.

Chinese language can use AlibabaPuHuiTi, https://www.alibabafonts.com/

I found that there is no problem with Chinese fonts on MacOS, but there are the above problems on Windows and Linux.

I'm running into the same issue, I feel it auto-translates Simplified Chinese into Traditional Chinese fonts, you can tell from the way of writing and the ones that didn't find the match properly displayed with a thinner font. I Hope Simplified Chinese can be 100% supported shortly.
