Description:
------------
simple string with no html has some characters stripped out.
seems the repackUTF7* functions do this.

Test script:
---------------
$parser =& new HTML_Safe();
$x = $parser->parse('a+b-c');
var_dump($x);

Expected result:
----------------
string(5) "a+b-c"

Actual result:
--------------
string(2) "ac"

I've to use next patch:

function repackUTF7($str)
{
return preg_replace_callback('!\+([0-9a-zA-Z/]{2,})\-!', array($this, 'repackUTF7Callback'), $str);
}

function repackUTF7Callback($r)
{
$str = base64_decode($r[1]);
if ($str === false)
{
return $r[1];
}
$str = preg_replace_callback('/^((?:\x00.)*)((?:[^\x00].)+)/', array($this, 'repackUTF7Back'), $str);
return preg_replace('/\x00(.)/', '$1', $str);
}
