see this thread on the language issue (which isn't one): [/t/19284/1](https://community.mp3tag.de/t/19284/1)

To fill the comment, create an action group with 2 actions:  
No. 1:  
Action of the type "Format value" for COMMENT  
Format string: %title%  
(This copies the contents of TITLE into COMMENT)  
No. 2:  
Action of the type "Format value" for COMMENT  
Format string: $regexp(%comment%,'._([._])',$1)
