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| * "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the |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