Remarks
Using the two-letter language abbreviation from the ISO Standard 639 and adding a third letter, such as “u” for the United States, creates the three- letter abbreviation.
You can also get the two-letter language abbreviation with GetLocaleInfo() by specifying LOCALE_SABBREVLANGNAME as the LCType. The abbreviated name ”enu” is returned for the English (US) language and is the same abbreviation that is returned with the LanguageDesignation property.
