Heres whats going on and i dont know if anyone has the answer but i will be as descriptive as possible.

I am using foobar2000 v0.9.6.7. I was trying to tag some of my audio files for the well known artist "AC/DC" and when i was trying to tag the files in foobar the program wouldn't allow me to. I would highlight and right click on the songs in foobar, and go to either file info or properties to tag the songs, plugging in "AC/DC" under the "Artist Name" in the Metadata tab after the program attempts at changing the artist name it comes back to the program reading "AC_DC" and i was wondering why it would do so. I'm using the "foo_masstag" component with this version of foobar and never really had any problems before. I have also tagged the files with the id3v1 and id3v2 and even the APEv2 mp3 tags, still with no luck. Does anyone know what im doing wrong? If im missing a symbols component or something? Thanks for the help in advance.

It looks like foobar2000 is trying to help you avoid "/"... since ID3v2.3 technically reserves this character as a multiple name separator (though it's rarely implemented). Not sure why you'd see it with APE tags. I'd need to test...

For parsing logic, I end up having explicit workarounds for "/" containing band names like AC/DC and +/-... and still allow the character to be used.

what kind of "work arounds" are you using?

Sorry, I'm talking about code... I end up having to maintain a hard list of bands with "/" in their name, so I don't split name apart as discrete entries when I parse the field. Use it for MP3 ID3v2.3 and AAC/M4A tagging... or any format that doesn't store "real" discrete entries.

Since the actual symbol is a lightning bolt, why not use:

ACDC

This is probably most commonly used and it's used at their site. Don't know if these would be problematic, certainly less useful, but better than AC_DC:

AC|DC

AC\DC

AC~DC

Just a thought.

Seeing as this was not posted in the foobar forum, I think it's appropriate to say that my AC/DC collection is tagged with ID3v1.1 and v2.3 as AC/DC, so possible player capabilities aside, at least for me this is completely a non-issue.

The KISS person that just posted has the character you need. AC/DC would look like this:

ACϟDC

I doubt it would translate on a device very well, probably show up as a solid cube, question mark or garbage, but at least it would look good on a web page.

i got no problems...
look just try few times ! and change the name from the foobar of course in windows you cant get "/" on folder name/or any other stuff
