ä -> Ä

[defdirk]

Hi there,

I would like to convert strings like "Gestüt" or "Präsenation" in uppercase. Normally it is no problem, but in Germany it is a problem. I read all manuals I could find, but there ist only the hint, not to use the parameter "C" but no hints what to use instead of.

$test = "Gestüt";
setlocale ("LC_CTYPE", "C");
strtoupper($test);
echo "$test";

--> GESTüT

but what's the alternative to "C"? Is there a list for all parameters and what's their job? Please help,

Thank you very much,

Dirk
