      Description

      The parserchecker (org.apache.nutch.parse.ParserChecker) calls URLUtil.toASCII on the url it is given, reencoding already percent-encoded URLs.

      For instance, let's say we want to query http://example.com, passing a GET parameter with name 'q' and value '/'. '/' is a special character, and thus has to be encoded before being sent.
      If we pass 'http://example.com/?q=/' to the parserchecker, then it doesn't encode the '/', and tries to fetch the URL as is, which is invalid.
      If we try to encode the parameter beforehand, and call the parsechecker with 'http://example.com/?q=%2F', then it encodes the '%' sign to '%25', and thus fetches 'http://example.com/?q=%252F'.

      This actually makes it impossible to fetch the correct URL (http://example.com/?q=%2F) from the parserchecker.
