Method

PangoOTInfofind_language

Declaration [src]

gboolean
pango_ot_info_find_language (
  PangoOTInfo* info,
  PangoOTTableType table_type,
  guint script_index,
  PangoOTTag language_tag,
  guint* language_index,
  guint* required_feature_index
)

Description [src]

Finds the index of a language and its required feature index.

If the language is not found, sets language_index to PANGO_OT_DEFAULT_LANGUAGE and the required feature of the default language system is returned in required_feature_index. For best compatibility with some fonts, also searches the language system tag ‘dflt’ before falling back to the default language system, but that is transparent to the user. The user can simply ignore the return value of this function to automatically fall back to the default language system.
