Menu fonts broken with disorder characters

Run on Windows 10 (build 17134) with Chinese language, menu fonts seem broken with disorder and unrecognizable characters, I tried to change IDE language setting to English and UI font configuration in lib\theme\theme.txt but still not work.

IDE menu display with default (Chinese) language setting:

IDE menu display with English language setting:

Settings windows and other text can be displayed in normal:

HI @kongwy ,
the font in use is fairly different from the "standard" Windows one which looks more like

Your system probably needs a font (not present by default with Chinese installation? ). Does garbled text also appear on a fresh portable installation?

Hi, @facchinm thanks for your help.

This problem appears in both instances installed by .exe or unzip from the compressed file. I tried changing font config in lib\theme\theme.txt but didn't help.

As you said, I just used Beyond Compare to compare the Fonts folder from my current Windows install and the one extracted from the install.wim from a Windows (Simplified Chinese Pro Edition) ISO. Basically, there are no differences except four TTF files of Yu Gothic have a newer version on my computer.

@SimonePDA we need to find a place to add the documentation about the fix (which is here facchinm@fb89a67 ) but can't be applied for everyone or the render would be terrible. Any hint?

@facchinm I already opened a task on Jira because with the new release of the IDE, the existing documentation is definitely obsolete. Maybe this information could be added to the refreshed "environment" docs. However I have no time schedule for that as it is in FT-Content hands for assignment and priority.
We document the IDE in these two places:
