I also tried this; Nautilus displayed the filename as expected, however the statusbar text read:
"SexyL(etyb 1) detceles "exe.jpg
Which was meant to look like this:
"SexyLgpj.exe" selected (1 byte)
Except that the whole thing got confused by the RTL marker. Also, when displayed by ls, it would only work if it happened to appear in the rightmost column, because any other filenames printed to the right of it get similarly corrupted. In my case it happened to say 'SexyLenO utnubU exe.jpg" (and the reversed 'Ubuntu One' folder was displayed in a different color because I have ls colors turned on). So it's pretty obvious either way that something fishy is going on, thankfully.
