Hello, i searched in the Forum but haven't find this bug.

I have version 2.80 of Mp3tag on Windows 10.

My goal was to replace rnb or r n b or r ' n b by RnB, so i used the following RegExp :  
$regexp(%comment%,r[']{0,2}n[]?b,RnB)  
But i have this error message :  
[SYNTAX ERROR IN FORMATTING STRING]

I think this is really a bug because the search worked with my favorite editor (PSPad) with the same RegExp (r[']{0,2}n[]?🕶.

Thanks for your help guys

For example this Formatstring works ...  
$regexp(%TEST%,'(rnb|r n b|r '''' n B)','RnB')

From:  
TEST=rnb or r n b or r ' n b by RnB  
To:  
TEST=RnB or RnB or RnB by RnB

Note the usage of the special single quote character **'** , which is the string delimiter within Mp3tag Scripting Language, ...  
to make it visible it has to be written twice.
