/* ### Data tables **************************************************/

/**
|
|
* Table of language codes, both 2- and 3-letter, with preference
|
|
* given to 2-letter codes where possible. Includes 3-letter codes
|
|
* that lack a 2-letter equivalent.
|
|
*
|
|
* This list must be in sorted order. This list is returned directly
|
|
* to the user by some API.
|
|
*
|
|
* This list must be kept in sync with LANGUAGES_3, with corresponding
|
|
* entries matched.
|
|
*
|
|
* This table should be terminated with a NULL entry, followed by a
|
|
* second list, and another NULL entry. The first list is visible to
|
|
* user code when this array is returned by API. The second list
|
|
* contains codes we support, but do not expose through user API.
|
|
*
|
|
* Notes
|
|
*
|
|
* Tables updated per http://lcweb.loc.gov/standards/iso639-2/ to
|
|
* include the revisions up to 2001/7/27 *CWB*
|
|
*
|
|
* The 3 character codes are the terminology codes like RFC 3066. This
|
|
* is compatible with prior ICU codes
|
|
*
|
|
* "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the
|
|
* table but now at the end of the table because 3 character codes are
|
|
* duplicates. This avoids bad searches going from 3 to 2 character
|
|
* codes.
|
|
*
|
|
* The range qaa-qtz is reserved for local use
