curly quotes not handled by htmlspecialchars?

[sneakyimp]

i have some data i'm dealing with that has those irritating curly double quotes (ascii 147 and 148). I would like to change these to either their html special code equivalents OR change them to ordinary double quotes.

as far as i can tell, neither htmlentities or htmlspecialchars will do this. am i mistaken or is there some trick to providing the right arguments that i'm missing?

PS: can you set both ENT_NOQUOTES and ENT_QUOTES at the same time? one appears to handle double quotes and the other appears to handle single quotes.

$string = 'this string has “curly quotes” in it';
$string = str_replace(chr(147), '"', $string);
$string = str_replace(chr(148), '"', $string);

thanks for your suggestion. i have this function. It's slow, but fortunately it only has to run once when i import the data.

function html_curly_quotes($text) {
  $result = $text;
  $result = str_replace(chr(145), "‘", $result);
  $result = str_replace(chr(146), "’", $result);
  $result = str_replace(chr(147), '“', $result);
  $result = str_replace(chr(148), '”', $result);


  return $result;
}

Seems to me a bit odd that htmlspecialchars won't handle curly quotes.
