Comment 88 for bug 105900

From a mail I sent today:

This is how I think this should be fixed:

Add a new element FC_NAME_LANG="namelang".

In FcFreeTypeQuery, perhaps set FC_NAME_LANG to the intersection of
FC_FAMILY_LANG and FC_STYLE_LANG. Or maybe don't. Not going to use this
directly.

In FcConfigDefault, if FC_NAME_LANG is empty, fill it in from default locale
language. Then if FC_FAMILY_LANG is empty, copy it from FC_NAME_LANG. Same
for FC_STYLE_LANG and FC_FULLNAME_LANG. This way, FC_NAME_LANG is how the
user will request names in a particular language.

In FcFontRenderPrepare, when deciding what FC_FAMILY and FC_STYLE to choose,
choose the first one that has a _LANG equivalent present in the query
pattern's respective _LANG element.

That should do it.
