| 64 | * Table of language codes, both 2- and 3-letter, with preference |
| 65 | * given to 2-letter codes where possible. Includes 3-letter codes |
| 66 | * that lack a 2-letter equivalent. |
| 67 | * |
| 68 | * This list must be in sorted order. This list is returned directly |
| 69 | * to the user by some API. |
| 70 | * |
| 71 | * This list must be kept in sync with LANGUAGES_3, with corresponding |
| 72 | * entries matched. |
| 73 | * |
| 74 | * This table should be terminated with a NULL entry, followed by a |
| 75 | * second list, and another NULL entry. The first list is visible to |
| 76 | * user code when this array is returned by API. The second list |
| 77 | * contains codes we support, but do not expose through user API. |

| 79 | * Notes |
| 80 | * |
| 81 | * Tables updated per http://lcweb.loc.gov/standards/iso639-2/ to |
| 82 | * include the revisions up to 2001/7/27 *CWB* |
| 83 | * |
| 84 | * The 3 character codes are the terminology codes like RFC 3066. This |
| 85 | * is compatible with prior ICU codes |
| 86 | * |
| 87 | * "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the |
| 88 | * table but now at the end of the table because 3 character codes are |
| 89 | * duplicates. This avoids bad searches going from 3 to 2 character |
| 90 | * codes. |
| 91 | * |
| 92 | * The range qaa-qtz is reserved for local use |
