Can anyone solve this for me?
MP3Tag works great everywhere. FB2K reads the tags fine. BUT, when you edit in FB2K, the changes fails to display correctly in MP3T.
For example, we use ';' as the de-limiter in the genre tag (eg: Rock; Cover'. This is fine, and FB2K reads them OK. However, when you edit that field in FB2K (it's just easier and quicker to do that sometimes!), then when the file is opened in MP3T, the ';' has become `\\` (eg: `Rock\\Cover`). This causes only the first tag to show in MP3T's Genre column (although the multiple tags do show in the Tag Panel when the song is selected). Hope all that makes sense?!!

Both programs can deal with multi-value fields.
MP3tag shows the separator as `\\`.
FB2k shows the separator as `;`.
If you want to see multi-value fields in a column, you have to enter as
Value: `$meta_sep(genre,\\)`

Thanks. Where would I enter `$meta_sep(genre,\\)` ?

See the columns definition and enter it as "value".

Brilliant! Thankyou.

Since my original post, I have found that this doesn't work in the Tag Panel. Is there any way to display multiple composers in comma-separated list there? I've done it in the Composer column OK. Quite a few songs have the composers delimited by [;space] in FB2K, which appears as [\] in MP3Tag Panel. When I try and do a Quick Convert [\] to [,], nothing happens as the Tag Panel is only displaying the first Composer tag. Thanks for any help.

OK, apologies, It looks as if I can combine the multiple tags using a different Quick Action task: merge tags. Thanks for superb software.

I do not think that it is necessary to merge the fields first if you want to edit them in the tag panel.
MP3tag displays them with the 2 `\\` so that as soon as you save the tag again, they would be transformed into multi-value fields again.
So you just have to either edit a substring or add data separated with `\\` from the rest.
It is true, though, that in action groups you have to merge the fields first, either with an action or with $meta\_sep()
