I don't know for sure, but I think it's not really due to Zen Photo but rather the way directories work. I had an image with a comma and it didn't work either.

I'm still seeing this in 1.0.2. Is it still a known issue? Any suggested fixes?
Yep, it's a known issue. I'm swamped right now, not finding any time to work on the next release, but once it does come out it should have this fixed.
Check the bugtracker, http://bugs.zenphoto.org to check the status.
Thanks. Sorry, I should've thought to check the bugtracker. Next time. :o)
Not sure if this will fix your issues, but I found a fix for my problems with question marks and commas : http://www.zenphoto.org:8080/browse/ZEN-4
