Re: [Bug: 21.4.12] mail-extr.el broken for ISO-8859-2

That will work in 21.4 as well as 21.5. Or Stephen> (as a heuristic), just use [^\000-\255] (you'd have to do that Stephen> as an alternative rather than a character class). I bet that Stephen> will work well enough in practice. Well, I can continue to kludge around this adding relevant characters myself, but... The current situation basically means that mail-extr is broken for anyone who doesn't use ASCII + ISO-8859-1. It breaks BBDB and Supercite for me. I'd consider it quite serious breakage. --J.
