// TODO: Get rid of these deprecated LCID Stuff (see "winnt.h"):
//
// ** DEPRECATED ** DEPRECATED ** DEPRECATED ** DEPRECATED ** DEPRECATED **
//
//  DEPRECATED: The LCID/LANGID/SORTID concept is deprecated, please use
//  Locale Names instead, eg: en-US instead of an LCID like 0x0409.
//  See the documentation for GetLocaleInfoEx.
//
//  A locale ID is a 32 bit value which is the combination of a
//  language ID, a sort ID, and a reserved area.  The bits are
//  allocated as follows:
//
//       +-------------+---------+-------------------------+
//       |   Reserved  | Sort ID |      Language ID        |
//       +-------------+---------+-------------------------+
//        31         20 19     16 15                      0   bit
//
//  WARNING: This pattern isn't always followed (es-ES_tradnl vs es-ES for example)
//
//  WARNING: Some locales do not have assigned LCIDs.  Please use
//           Locale Names, such as "tlh-Piqd".
//
//  It is recommended that applications test for locale names rather than
//  attempting to rely on LCID or LANGID behavior.
//
//  DEPRECATED: Locale ID creation/extraction macros:
//
//    MAKELCID            - construct the locale id from a language id and a sort id.
//    MAKESORTLCID        - construct the locale id from a language id, sort id, and sort version.
//    LANGIDFROMLCID      - extract the language id from a locale id.
//    SORTIDFROMLCID      - extract the sort id from a locale id.
//    SORTVERSIONFROMLCID - extract the sort version from a locale id.
//
//  Note that the LANG, SUBLANG construction is not always consistent.
//  The named locale APIs (eg GetLocaleInfoEx) are recommended.
//
//  DEPRECATED: LCIDs do not exist for all locales.
//
