I am Japanese. Please teach me how to convert Japanese song titles entered with Unicode combining characters.  
In Japanese, there are combining characters. For example, the character "PO" can be represented not only as 30DD but also as 30DB 309A.  
An example is attached in the image.

Currently, the song titles are stored in a decomposed state.  
Unfortunately, the player I have cannot display these characters correctly.  
Therefore, I would like to use Mp3tag to convert the song titles into a composed state.

Thanks

This may turn into a laborious task.  
In a format string, you could enter something like  
`$replace(%title%,$char(12509),$char(12507) $char(12442))`  
which would lead to ホ ゚  
$replace() allows some 30 pairs of search and replace.
