Hi,

> of course we accept any workaround function.

You're welcome to rename it! :)


<?php function htmlspecialchars_workaround($str, $quote =3D
ENT_COMPAT, $charset =3D 'iso-8859-1') {

        if (in_array(strtolower($charset),
array('iso-8859-2', 'iso8859-2', 'latin-2', 'latin2'))) {

                if (! ($quote & ENT_NOQUOTES)) {
                        $str =3D str_replace("\"", "&quot;",
$str);
                }

                if ($quote & ENT_QUOTES) {
                        $str =3D str_replace("\'", "&#039;",
$str);
                }

                return str_replace(array("<", ">", "&"),
array("&lt;", "&gt;", "&amp;"), $str);
        }
        else {
                return htmlspecialchars($str, $quote, $charset);
        }

} ?>

Why is it enough to simply replace <, > and &?  Because
8859-2 is an 8 bit wide encoding, so each byte is a single
char, and each str*() function is applicable on it. If you
replace these three chars to &lt; &gt; and &amp;, all other
latin2 characters will be ready to display in an HTML
document using charset=3Diso-8859-2.  No one else can
hide or modify the meaning of the chars than the <, >
and & signs.

mm.
