/* For more information on the Apple locale concept please refer to
|

http://developer.apple.com/documentation/CoreFoundation/Conceptual/CFLocales/Articles/CFLocaleConcepts.html
|
||||
According to this documentation a locale identifier has the format: language[_country][_variant]*
|
||||
e.g. es_ES_PREEURO -> spain prior Euro support
|
||||
Note: The calling code should be able to handle locales with only language information e.g. 'en' for certain
|
||||
UI languages just the language code will be returned.
