Subject: Windows default font glyphs are rendered wrong on some systems
Hello,

for some of our users, the font glyphs of the default Windows font are wrong by an offset of +2. E.g. the letter D is rendered as F, the symbol - is rendered as /, and so on ... However, the glyph spacings and kernings are using the correct values for the original letter, only the actual glyph itself is wrong. This is happening on the latest 24-ea build on Windows 11, but also occurred on version 21 a while ago. I wasn't able to reproduce it myself, only some users were.
This has happened now for multiple users of our application, so I figured to report it (Didn't find this in the bug tracker).

Here is there issue, next to how it should look like:
[cid:part1.1kRBhQ05.RLwnvj8o at xpipe.io]

[cid:part2.a5C3DfO5.gpCzH0gk at xpipe.io]

(It is in danish because the user played around with the language settings to troubleshoot)

There was no explicit -fx-font set, so the application uses the default one. When the users change to using -fx-font: Roboto, which is bundled with our application, the glyphs are rendered normally. So this issue is specific to certain fonts.

If there's any additional information required, I can relay that request to our affected users.

Best
Christopher Schnick
