There are many standardized code sets—R’s countrycode package lists around 30—but only two are commonly used: 2 and 3 letter ISO codes. Of these, you should always use the 3 letter codes (technically ISO 3166-1 alpha-3). Why # There are only 26 English letters, so the space of 2 letter combinations has only 26 × 26 ≈ 600 codes. 1 Control-C has typically been used as a "break" or "interrupt" key. 2 Control-D has been used to signal "end of file" for text typed in at the terminal on Unix / Linux systems. Windows, DOS, and older minicomputers used Control-Z for this purpose. 3 Control-G is an artifact of the days when teletypes were in use. This alpha-2 ISO 639-1 code was approved in 1999 and included in ISO 639-1: 2002. It was mistakenly missing in earlier versions of the tables on the ISO639-2 web site. As of January 2003, it has been included. av: ava: Avaric: avar: 1999-08-16: Add: This alpha-2 ISO 639-1 code was approved in 1999 and included in ISO 639-1: 2002. This table lists all of: ISO 639-1: two-letter codes, one per language for ISO 639 macrolanguage. And some of: ISO 639-2/T: three-letter codes, for the same languages as 639-1. ISO 639-2/B: three-letter codes, mostly the same as 639-2/T, but with some codes derived from English names rather than native names of languages (in the following table See the ISO 3166-3 standard for former country codes.

The ISO 639 is International Organization Standard for language codes which are used to establish internationally recognized codes for representation of languages. ISO Punjabi Language codes may be two letter codes or three letter codes. The ISO language codes were approved in 1967. ISO Punjabi Language codes are : ISO 639-1 code, ISO 639-2 The ISO 639 is International Organization Standard for language codes which are used to establish internationally recognized codes for representation of languages. ISO Bengali Language codes may be two letter codes or three letter codes. The ISO language codes were approved in 1967. ISO Bengali Language codes are : ISO 639-1 code, ISO 639-2 Language Culture Names, Codes, and ISO Values. RAD Studio includes a suite of Translation Tools to facilitate localization and development of Win32 applications for different locales. When you add a new language to your project, the Resource DLL Wizard generates a resource module project for this language and add it into your project group. I usually steer clear of encoding stuff into the file name. If for no other reason, using the 3-character ISO-639 variant isn't perfect unless you strictly specify which variant you are using - ISO-639-2/B, ISO-639-2/T, or ISO-639-3. If you need to provide locale-specific variants, then you should take a close look at RFC3066. Basically, you If you want to persist a RegionInfo object or communicate it between processes, you should instantiate it by using a full culture name rather than a two-letter ISO region code. Because RegionInfo properties depend on script and language, instantiating a RegionInfo object by using only a region code loses context and data.
