/**
* 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 nullptr entry, followed by a
* second list, and another nullptr 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
*
* 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* "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the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
