language_from_string

Convert a language tag to a `PangoLanguage`.

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 [[email protected]_default] if you want to get the `PangoLanguage` for the current locale of the process.

Parameters:

language

a string representing a language tag

Returns:

a `PangoLanguage`
