> another last solution : build a tar-file containing all the "bad-named" files. But it's just good fro storage, not using.

You could build an ISO file and mount it using loopback to get read access to individual files.

Do you need to read the stick on Windows? If not, format it ext2 (not ext3, for some reason to do with journals and flash I forget), then you're doing things the right way.
