## NAME
    [CGI::Simple::Util](https://www.chedong.com/phpMan.php/perldoc/CGI%3A%3ASimple%3A%3AUtil/markdown) - Internal utilities used by [CGI::Simple](https://www.chedong.com/phpMan.php/perldoc/CGI%3A%3ASimple/markdown) module

## SYNOPSIS
        $escaped     = escapeHTML('In HTML you need to escape < > " and & chars');
        $unescaped   = unescapeHTML('&lt;&gt;&quot;&amp;');

## DESCRIPTION
    [CGI::Simple::Util](https://www.chedong.com/phpMan.php/perldoc/CGI%3A%3ASimple%3A%3AUtil/markdown) contains essentially non public subroutines used by [CGI::Simple](https://www.chedong.com/phpMan.php/perldoc/CGI%3A%3ASimple/markdown). There are
    HTML and URL escape and unescape routines that may be of some use.

    An internal object is used to store a number of system specific details to enable the escape
    routines to be accurate.
