• create a file whose filename contains U+FFFD (replacement character)
• try to add it to picard
• picard seems to pass the wrong filename to mutagen, making it impossible to process the file further

 

Note that mutagen-inspect run on the same file does not fail, so I'm guessing that Picard somehow convert the character to a regular '?'.
