Unrecognized escape \\%c in character class passed through in regex; marked by <-- HERE in m/%s/

(W regexp) You used a backslash-character combination which is not recognized by Perl inside character classes. The character was understood literally, but this may change in a future version of Perl. The <-- HERE shows in the regular expression about where the escape was discovered.
