       uri_escape - Escape unsafe characters

       uri_unescape - Unescape escaped characters

        use URI::Escape;
        $safe = uri_escape("10% is enough\n");
        $verysafe = uri_escape("foo", "\0-\377");
        $str  = uri_unescape($safe);

       This module provide functions to escape and unescape URI strings.  Some
       characters are regarded as "unsafe" and must be escaped in accordance
       with RFC 1738.  Escaped characters are represented by a triplet
       consisting of the character "%" followed by two hexadecimal digits.

       The uri_escape() function takes an optional second argument that
       overrides the set of characters that are to be escaped.  The set is
       specified as a string that can be used in a regular expression
       character class (between [ ]).  E.g.:

         \x00-\x1f\x7f-\xff          # all control and hi-bit characters
         a-z                         # all lower case characters
         ^A-Za-z                     # everything not a letter

       The default set of characters to be escaped is:


       The module can also export the %escapes hash which contains the mapping
       from all characters to the corresponding escape code.
