My locale is en_US and I have had general font problems for multiple
applications, including gimp, gourmet, and icecat, so I do not think it is
necessarily related to the locale. I think a lot of it is user-level
configuration. When I use gnome tweaks to change the fonts, I find that some
fonts work as expected, but some do not. In particular, I notice that if I
remove a font, it is not removed from the list of fonts I can select.
Perhaps there's a local database of available fonts that isn't modified when
a font is uninstalled with guix?
