Hi,
I noticed that the default font is hard-coded to be Arial Regular, yet for some reason my system's locale was set to German (de-DE) and it reported the font names as "Arial Standard", "Arial Kurziv" (italic) and "Arial Fett" (bold). It required a change to the system's locale and a shutdown + boot to reset this back to "Arial Regular". See also: https://www.isunshare.com/windows-10/change-system-locale-in-windows-10.html
This causes a crash on startup, also due to a bug in FontManager.cpp where it does not return a proper error if SystemFonts::getFontBuffer() returns a nullptr.
I don't know how to obtain localized font names properly, instead of using hard-coded names. So we may be out of luck on this one. But I just thought I'd mention it.
