I've attached a testcase. Open it under, say, UTF-8 locales, and with
$thorough_search variable unset (the problem doesn't occur when it is
set). Then limit to "~Bé". Only the message "body in utf-8" is found.
Note: I wonder why Mutt doesn't encode the regexp in the encoding of
the message / body part (any time it finds a new encoding). IMHO, that
would be faster than decoding the body part as the number of different
encodings remain limited in practice.
Note that the manual says:
Users searching attachments or for non-ASCII characters should set this
value because decoding also includes MIME parsing/decoding and possible
character set conversions. Otherwise mutt will attempt to match against
the raw message received (for example quoted-printable encoded or with
encoded headers) which may lead to incorrect search results.
but this is worse than that. For instance, I need to set
$thorough_search to search for some strings with ASCII characters
only, when such strings contain a space, as some mailers encode
all spaces as =20 (more generally they can also occur at the end
of a line).
