This is needed so Python scripts can get built-in colors using the
SETTINGS_MANAGER.GetColorSettings() member.
Otherwise calling it with a built-in name crashes.
ttf fonts can declare multiple language names. Many by default opt to just declare one and not tag it any particular language.
However, there are CJK languages that typically leverage this function the most. They'll tag both a "en" and a cjk lang family name in CJK characters.
To be as user friendly as possible, we need to display said fonts in the CJK languages if KiCad to set to such a locale.
