Encoding of $appdata on XP?

[Malte Brill]

Hi there,

I need to read out $appdata on XP. As long as there are no Umlauts all  
is fine. As soon as there is an umlaut it breaks:

Username: ßäöütz é

specialfolderpath(26): C:/Dokumente und Einstellungen/ßäöütz é/ 
Anwendungsdaten
$appdata: C:\Dokumente und Einstellungen\á„”tz  
‚\Anwendungsdaten

I need $appdata, because the path for specialfolderpath(26) does not  
necessariely exist in a citrix environment.

Any ideas how to make sense out of the gibberish?
