The proposed patch adds the htmlcharrefreplace_errors() function which implements the "htmlcharrefreplace" error handler in the html module. This error handler is almost same as the "xmlcharrefreplace" error handler, but first try to replace an unencodable character to HTML named character reference. Result is a little more human-readable than with "xmlcharrefreplace".
