When using 
$wgLanguageCode = "zh_hant";

When click "登入／建立新賬號" (in English should be Login / Create User), link, the page render fail.

It go to a URL 
http://localhost/mediawiki/index.php?title=Special:%C7%94%A8%E6%88%B7%E7%99%BB%E5%85%A5&returnto=%E9%A6%96%E9%A0%81

(instead of the normal should be : 
http://localhost/mediawiki/index.php?title=Special:%E7%94%A8%E6%88%B7%E7%99%BB%E5%85%A5&returnto=%E9%A6%96%E9%A0%81

attention, after 'Special' is different, from %E7, go to %C7)


I have trace that, this different is come from the php function ucfirst(), at the file ./include/SpecialPage.php (about line 584).

And I just make a hot fix 
FROM
    return ucfirst( $name );
TO
    return $wgContLang->ucfirst( $name );

By now on, every thing seem OK.
