The O’Riley book “mastering regular expressions” has a whole section dedicated to it. As well as several tables. But it would be nice to have an online version.

And it's one one the best O'Reilly books. I went and checked because of your comment and just noticed there was a third edition that I missed, I have the second. Still a book worth studying.
