When I correct a filename to remove various illegal characters (like replacing “&” with “and”… or when accents are replaced with “?” (Dond� = Dond?) iTunes will not be able to locate the file new file. This does not happen with simple text.
“Sam & M�x” will break iTunes link when renamed to “Sam and M?x”
“Fate of Atlantis” re-links just fine when renamed. Even with a complex-ish mask like “02_13 - Fate_of_Atlantis-LucasArts-(1996)”
