Comment	> In the Native Language Support file Nls.php:280 [1] the language code > is trimmed to two characters. Probably under the assumption that > language codes are always ISO 639 and all character after that are > country subtags. But RFC 3282 [2} and RFC 3066 [3] clearly allow > three letter language codes from ISO 639-2 and some reserved codes. > > This excludes languages as important as Cebuano (ceb) with 30 million > speakers in the Philippines and even misinterprets Cebuano as Chechen > (ce). > > I came across this error when the accept-language mail header for Low > German (nds) was misreported as North Ndebele (nd). > > The correct fix is to allow all valid language codes.
