Apart from these three conditions, even if fontconfig knows the
language, is it necessary that fcfreetype.c has MAC language code
defined for that language, in order to list it in gdm?
When I tried adding .orth file, the "fc-list fontname lang" listed the
appropriate language, but still it did not appear in gdm list until,
the definitions were made in fcfreetype.c and ttnameid.h.
I don't know offhand why that would be. Here is the code that gdm
uses to determine if a language has sufficient font support:
pattern = FcPatternBuild (NULL, FC_LANG, FcTypeString, language_code,
NULL);
if (pattern == NULL)
goto done;
object_set = FcObjectSetBuild (NULL, NULL);
if (object_set == NULL)
goto done;
font_set = FcFontList (NULL, pattern, object_set);
if (font_set == NULL)
goto done;
is_displayable = (font_set->nfont > 0);
