The language tag must be in a RFC-3066 format. PangoLanguage pointers
can be efficiently copied (copy the pointer) and compared with other
language tags (compare the pointer.)
This function first canonicalizes the string by converting it to
lowercase, mapping '_' to '-', and stripping all characters other
than letters and '-'.
Use [type_func@Pango.Language.get_default] if you want to get the PangoLanguage
for the current locale of the process.

PangoLanguage structure, or %NULL if @language was %NULL. The
returned pointer will be valid forever after, and should not be freed.
