I have had trouble browsing music folders of USB drive attached to the Touch that had non-ASCII unicode characters encoded by UTF-8. I think it has to do with either the setup or the kernel of the Unix coming with the Touch. When I ssh into the touch, and type "ls", it pops up something like this:
ls ./directory/file
No such file
when either directory or file had accented characters or other non-ASCII characters. In some cases even I did not see any non-ASCII characters the file is still reported to be missing.

My question is, is there a modest upper limit for the number of characters in each file? The characters are showing correctly in my Mac Terminal or Linux machine, meaning they are correctly encoded in UTF-8.
