I am running a QNAP system and I am trying to move a huge music library from one server to another.
Unfortunately many .mp3 files and folder names contain � (U+FFFD REPLACEMENT CHARACTER) instead of the original hyphen ('). This is probably due to an old transfer I did many, many years ago.
The problem is that the move (to a CFS/SMB folder) is aborted and I need to open a shell and manually rename the file/folder to take out that special character.
On qnap (limited) shell I see the name file for example as:
Eric Clapton�s Concert/Knockin� Heavens Door.mp3
I want to avoid to manually rename each file.
I have found many suggestions/examples, but none with this special character (which I do not know how to refer to).
