/**
|
|
|
|
* A locale name is based on the language tagging conventions of RFC 4646 (Windows Vista
|
|
|
|
* and later), and is represented by LOCALE_SNAME.
|
|
|
|
* Generally, the pattern <language>-<REGION> is used. Here, language is a lowercase ISO 639
|
|
|
|
* language code. The codes from ISO 639-1 are used when available. Otherwise, codes from
|
|
|
|
* ISO 639-2/T are used. REGION specifies an uppercase ISO 3166-1 country/region identifier.
|
|
|
|
* For example, the locale name for English (United States) is "en-US" and the locale name
|
|
|
|
* for Divehi (Maldives) is "dv-MV".
|
|
|
|
*
|
|
|
|
* If the locale is a neutral locale (no region), the LOCALE_SNAME value follows the
|
|
|
|
* pattern <language>. If it is a neutral locale for which the script is significant, the
|
|
|
|
* pattern is <language>-<Script>.
|
|
|

* More at https://msdn.microsoft.com/en-us/library/windows/desktop/dd373814(v=vs.85).aspx
|
|
|
|
*
|
|
|
|
* Most of the languages we support are neutral locales, so we want to use the language name.
|
|
|
|
* There are three exceptions, zh-CN, zh-TW and pt-BR.
