the _encodeText() function is not utf8-safe

At http://us2.php.net/manual/en/function.ord.php#46267 is a uniord function that apparently correctly encodes UNICODE characters.

I've pasted it here:

/**
 * @Algorithm: http://www1.tip.nl/~t876506/utf8tbl.html
 * @Logic: UTF-8 to Unicode conversion
 **/
function uniord($c)
{
  $ud = 0;
  if (ord($c{0})>=0 && ord($c{0})<=127)
   $ud = ord($c{0});
  if (ord($c{0})>=192 && ord($c{0})<=223)
   $ud = (ord($c{0})-192)*64 + (ord($c{1})-128);
  if (ord($c{0})>=224 && ord($c{0})<=239)
   $ud = (ord($c{0})-224)*4096 + (ord($c{1})-128)*64 + (ord($c{2})-128);
  if (ord($c{0})>=240 && ord($c{0})<=247)
   $ud = (ord($c{0})-240)*262144 + (ord($c{1})-128)*4096 + (ord($c{2})-128)*64 + (ord($c{3})-128);
  if (ord($c{0})>=248 && ord($c{0})<=251)
   $ud = (ord($c{0})-248)*16777216 + (ord($c{1})-128)*262144 + (ord($c{2})-128)*4096 + (ord($c{3})-128)*64 + (ord($c{4})-128);
  if (ord($c{0})>=252 && ord($c{0})<=253)
   $ud = (ord($c{0})-252)*1073741824 + (ord($c{1})-128)*16777216 + (ord($c{2})-128)*262144 + (ord($c{3})-128)*4096 + (ord($c{4})-128)*64 + (ord($c{5})-128);
  if (ord($c{0})>=254 && ord($c{0})<=255) //error
   $ud = false;
 return $ud;
}

I plan to try it later to see if it actually works as advertised, but wanted to update this ticket.
