In my music collection, many artists and song names have characters with accents, tildes, etc.  Such as Antonín Dvořák or Béla Bartók.  If I scan my music collection without specifying the iTunes XML file, but rather just the direct path to my music files, all of my music shows up.

However, if I turn on iTunes support and specify the iTunes Library XML file, all of my music shows up EXCEPT for those containing these special characters (for example, I see everything by Barber but nothing by Bartók).  I would like to be able to use the iTunes XML file as the source for my library in order to access iTunes playlists and volume normalization, but because of this problem I cannot.

I am using the latest version of iTunes (7.3 I believe) and SlimServer 6.5.4.  The problem is not new to these versions, however, as I've had the issue for a long time.  I run SlimServer on SuSE Linux 10.0 and map to the iTunes Library XML file through a Samba share.
