-- | Returns the t'GI.Pango.Structs.Language.Language' for the current locale of the process.
-- Note that this can change over the life of an application.
-- 
-- On Unix systems, this is the return value is derived from
-- \<literal>setlocale(LC_CTYPE, NULL)\<\/literal>, and the user can
-- affect this through the environment variables LC_ALL, LC_CTYPE or
-- LANG (checked in that order). The locale string typically is in
-- the form lang_COUNTRY, where lang is an ISO-639 language code, and
-- COUNTRY is an ISO-3166 country code. For instance, sv_FI for
-- Swedish as written in Finland or pt_BR for Portuguese as written in
-- Brazil.
-- 
-- On Windows, the C library does not use any such environment
-- variables, and setting them won\'t affect the behavior of functions
-- like @/ctime()/@. The user sets the locale through the Regional Options
-- in the Control Panel. The C library (in the @/setlocale()/@ function)
-- does not use country and language codes, but country and language
-- names spelled out in English.
-- However, this function does check the above environment
-- variables, and does return a Unix-style locale string based on
-- either said environment variables or the thread\'s current locale.
-- 
-- Your application should call \<literal>setlocale(LC_ALL, \"\");\<\/literal>
-- for the user settings to take effect.  Gtk+ does this in its initialization
-- functions automatically (by calling @/gtk_set_locale()/@).
-- See \<literal>man setlocale\<\/literal> for more details.
