Distribution of files containing an € (euro) sign in the name

We have in our distribution a file with a eurosign in the filename. In the
logfile there is an entry with following message:
Gather (name of distribution) stopped with error - the file (name of file)
could not be read, therefore, it could not be gathered. (IO error)
The eurosign in the filename shows up as an ? (questionmark) in the above
errormessages.
If we remove the file then the distribution will be succesfully gathered
and distributed.

Is this a knownerror, am I doing something wrong, please, help. I have
searched the knowledge base, but found nothing.

Thanks,

Erik
