I would have thought iTunes would display an error message if fed a file it couldn't handle.
If iTunesEncode gets an error from the call to iTunes, then it will spit out an "Error of some kind occured at such and such point" and return an error code to the shell. So if the calling program is checking error codes, it will know something fouled up. This assumes the calling program checks the error code, though. EAC can check those, but doesn't necessarily have to (I think it's a setting somewhere).
In any case, it will probably make iTunesEncode spit out an error message, but the message won't be particularly informative.
