Ezio Melotti <ezio.melo...@gmail.com> added the comment: I took a look to what other languages do, and it turned out that:
perl escapes [^A-Za-z_0-9] [0]; .net escapes the metachars and whitespace [1]; java escapes the metachars or escape sequences [2]; ruby escapes the metachars [3]; It might be OK to exclude _ from the escaped chars, but I would keep escaping all the other non-alnum chars too (i.e. match perl behavior). (FWIW, I don't think re.escape() is used in performance-critical situation, so readability should probably be preferred over speed.)
