*
|
|
* 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* "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the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
