We are only the default global FcConfig created by calling FcInitLoadConfigAndFonts inside FcInit().
Calling FcInitLoadConfigAndFonts does nothing but creating another FcConfig option that never gets disposed or used because we use the FcConfig functions with null
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.

If the font face doesn't include a Bold or Italic version, we still want
to display the font as bold/italic, so we fake it with freetype.
This also prevents recurring error messages where the outline font warns
about "substitutes" within the same font family.
Also allows variants on the weight descriptor to be used without
throwing a substitution warning
