Hmm. I think I see the way through here. See below.

Yes. The representation of the names internally includes all of the
localized names along with the postscript name (which is always ASCII), any
match or list result will include all of these names. I would sort the
names so that any English or Latin names would come first in the list.
Ok, so applications want a notion of 'canonical' family names which can be
mapped to localized names for display to the user at runtime. I plan on
storing all of these names together in the same FC_FAMILY entry for each
known font, tagged (somehow) with the associated language. The entries
would be sorted with English names first, followed by names containing only
Latin characters and then the remaining names following sorted by language
tag.
A naïve application using the existing FcPatternGetString API will get an
English name for each font. A separate API (FcPatternGetLangString?) would
walk the list of names and select the one best matching the specified
language (or current locale).
An application wishing to store font preferences in a locale-insensitive
fashion can either:
a) Store just the English name. Converting to a local name would
require a call to FcFontList and then a call to
FcPatternGetLangString.
b) Store all of the names along with their languages. This can
be done with FcNameUnparse/FcNameParse which generate UTF-8
encoded strings for the font name.
