Could someone direct me to any documentation of the Mp3tag-proprietary reserved characters/strings in property values?

Even the one I know about - \\ - I cannot find documented.

Thanks.

At the moment, only \\ comes to my mind. I'll see if I find a good place in the help file to document this.

If you have suggestions, please let me know.
