The following is an error that one of the guys at my office found today.

This is the code snippet that generated the problem... 

        echo ("btnText:$btnText<BR>"); 
        $text = strtoupper(xlat($btnText)); 
        echo ("text:$text<BR>"); 

... where the value of xlat($btnText) is "Nästa". 

It appears that `strtoupper()` will sometimes produce "NäSTA" and
sometimes the "a" will be correctly uppercased.

Which version of PHP? And what are the locale settings (envs) like?
AFAIK a similar case was reported and fixed already.
