Yes, I read that. But I don't see anywhere in that manual where it says anything to the effect of "the search is case sensitive if your $charset is UTF-8, and case insensitive if it is us-ascii." Am I missing something else that is documented there? As my original post indicated, and illustrated by example, the problem is not related to an uppercase letter; there are none in the search patterns I am using. The case sensitivity of the regexp seems to be linked to the LC_ environment variables and/or the $charset in Mutt.
