in thread Substitute \W but not \.

Are you sure? perlunicode says
(However, and as a limitation of the current implementation, using "\w" or "\W" inside a "[...]" character class will still match with byte semantics.)
which means that [^\w] is not the same as \W.

    Well, logically, those are arguably the same (at least, have been since day two), so I'd call the current implementation "buggy" if it can't make those the same.

    But thanks, I was unaware of this bug.
