Importing .cue sheet with Japanese characters (UTF-8)

I am pleasantly surprised that Mp3tag can expand a CUE file to create lines in the file list that contain the tags for the corresponding files.
Maybe that is an undocumented feature. It's news to me.
But that means Mp3tag (ie Florian) has done all the heavy lifting when tagging files using a CUE file.

There is no need to parse the CUE file, as I suggested earlier.
Instead, we can easily copy the tags from the list created from the CUE file to the individual WAV files.
That means the CUE file must be added to Mp3tag with all the WAV files that were split by using it.
