Looks like a problem with locales or may be even a bug in the regex parser in mutt. Now setting LC_ALL usually overrides all other LC_ variables. So try to only set LC_CTYPE or may be LC_COLLATE to C. I am not sure if this works, but it is worth a try. > > Then the regex problem is solved, but other problems are introduced since > Mutt is now running with us-ascii as the $charset. True.

Does anyone know how I can run > mutt in UTF-8 and without these case problems in regular expressions? Well, if you do not find a solution, you could open a bug report. regards, Christian -- :wq
