Hmm. There's something going on here that we don't know about. My guess is
you're using something like:
$word = '#blah\\';
s/(\s|^)$word(?=\s|$)//;
where the problem would be that your variable is simply being copied
verbatim into the string, and so escaping the character immediately
following. Like this:
s/(\s|^)#blah\(?=\s|$)//;
which clearly changes the meaning of the following look-ahead expression (?=
... ). Try:
s/(\s|^)\Q$word\E(?=\s|$)//;
which quotes the entire contents of your variable, which can then contain
any charatcers with impunity.
If this isn't what you're doing, let us know.
Cheers,
Rob
