Up until the latest release (2.27) I have been able to use square brackets in the Tag-\>Filename function or mp3tag successfully. I have a naming convention i use (%track%. %title% - [%artist%].mp3) for all my mp3's and wish to continue this practice (10,000+ mp3s)
I assume this is a bug if not, is there a way i can continue to do this?

If you put backticks around the square brackets, it should work.
%track%. %title% - '[' %artist% ']'
**Edit:** This is also explained inside the [help](https://docs.mp3tag.de/scripting) file and the [What's new?](https://docs.mp3tag.de/getting-started/release-notes) document which popped up after installing MP3Tag 2.27.

nice work. Works a treat. Any reason why this changed?

This change is part of the new parser. I guess Florian can go into the details if you want.

I had to rewrite the whole parser, because the old one has major issues with backslashes and double quotes. One new feature of the new parser (which behaves almost like [foobar2000's](http://foobar2000.org) TAGZ) is the conditional nature of the square brackets. I like it 🙂
