Additional info:

From http://www.php.net/manual/en/ref.mbstring.php,
> For PHP 4.3.3 or before, To enable that feature, you will have to supply either 
> one of the following options to the LANG parameter of --enable-mbstring=LANG; 
> --enable-mbstring=cn for Simplified Chinese support, --enable-mbstring=tw for 
> Traditional Chinese support, --enable-mbstring=kr for Korean support, 
> --enable-mbstring=ru for Russian support, and --enable-mbstring=ja for Japanese 
> support (default). To enable all supported encoding, use --enable-mbstring=all.

php.spec specifies only --enable-mbstring (not --enable-mbstring=all). Therefore
mbstring supports only Japanese.
