Hi Michael,

turned out the non ascii characters wasn't the only problem in that case. I modified your script to also remove slashes and colons. Even then the fbx didn't work. After several hours digging through lists of object names, trying to find any suspicious characters I stopped. Possibly the length of the names was also a problem, I don't know. I changed the script again to remove object names *entirely* and then it worked.
Since I don't absolutely need the object names, I"m happy with that.

Thanks again for your help. Btw the new feature having materials exported in fbx is very useful!

Sven
