Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

It depends just what you mean by ``escape''. URL escapes are dealt with in the perlfaq9 manpage. Shell escapes with the backslash (\) character are removed with:

    s/\\(.)/$1/g;

This won't expand "\n" or "\t" or any other special escapes.
