71 * that lack a 2-letter equivalent.
72 *
73 * This list must be in sorted order. This list is returned directly
74 * to the user by some API.
75 *
76 * This list must be kept in sync with LANGUAGES_3, with corresponding
77 * entries matched.
78 *
79 * This table should be terminated with a NULL entry, followed by a
80 * second list, and another NULL entry. The first list is visible to
81 * user code when this array is returned by API. The second list
82 * contains codes we support, but do not expose through user API.
83 *
84 * Notes
85 *
86 * Tables updated per http://lcweb.loc.gov/standards/iso639-2/ to
87 * include the revisions up to 2001/7/27 *CWB*
88 *
89 * The 3 character codes are the terminology codes like RFC 3066. This
90 * is compatible with prior ICU codes
91 *
92 * "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the
93 * table but now at the end of the table because 3 character codes are
94 * duplicates. This avoids bad searches going from 3 to 2 character
95 * codes.
96 *
97 * The range qaa-qtz is reserved for local use
