84/**
85 * Table of language codes, both 2- and 3-letter, with preference
86 * given to 2-letter codes where possible. Includes 3-letter codes
87 * that lack a 2-letter equivalent.
88 *
89 * This list must be in sorted order. This list is returned directly
90 * to the user by some API.
91 *
92 * This list must be kept in sync with LANGUAGES_3, with corresponding
93 * entries matched.
94 *
95 * This table should be terminated with a NULL entry, followed by a
96 * second list, and another NULL entry. The first list is visible to
97 * user code when this array is returned by API. The second list
98 * contains codes we support, but do not expose through user API.
99 *
100 * Notes
101 *
102 * Tables updated per http://lcweb.loc.gov/standards/iso639-2/ to
103 * include the revisions up to 2001/7/27 *CWB*
104 *
105 * The 3 character codes are the terminology codes like RFC 3066. This
106 * is compatible with prior ICU codes
107 *
108 * "in" "iw" "ji" "jw" & "sh" have been withdrawn but are still in the
109 * table but now at the end of the table because 3 character codes are
110 * duplicates. This avoids bad searches going from 3 to 2 character
111 * codes.
112 *
113 * The range qaa-qtz is reserved for local use
