pdfcreator on citrix server can not write to a local directory in Serbian Cyrillic alphabet

Hello,

I'm using the pdfcreator on a citrix server. (1.7.3).
Verything
is working well, but when we want to save the pdf to a local drive
(through the citrix receiver) and the local directory has special
characthers, the file isn't writen?

The clients are usingSerbian Cyrillic alphabet.
Is pdfcreator not utf8 aware?

Is there a fix?

Thanks,

Roel Niesen
