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);
