In addition, the undocumented "neutral" is also accepted as a valid language setting. That is also the default value if the INI setting is not set:
( mb_language( 'neutral' ) );     // TRUE; accepted as language string
var_dump( mb_language() );                    // 'neutral'

The documentation of this particular INI setting and function is ambiguous.

In PHP 5.3, mb_language() returns "neutral" by default for me.
