Problems with accented characters

Yesterday I had a hard fight against this module due to this problem. Finally, I think I came up with the error.

Initially, it may seem the problem is the module doesn't tell to Textile to work with UTF-8 encoding, which is the one used by Drupal.

It should be fixed in the code at the end of the module, inside the DrupalTextile class. (This is because all Drupal processing is supposed to deal with UTF-8).

One way to do so would be changing the next code (from line 516):

    function process($in_string) {
    return preg_replace('{(<a href=")(#[^"]*")}', '$1' . request_uri() . '$2', parent::process($in_string));
  } // function process

Should be changed to this:

    function process($in_string) {
    $this->charset('utf8'); // This is the important change
    return preg_replace('{(<a href=")(#[^"]*")}', '$1' . request_uri() . '$2', parent::process($in_string));
  } // function process

However, this is not enough. There is an error in the textilephp/Textile.php as well. The author forgets that in PHP, 0 !== NULL but 0 == NULL. This happens in the next piece of code (from line 4080):

  function char_encoding($char_encoding = NULL) {
    if ($char_encoding != NULL) {
      $this->options['char_encoding'] = $char_encoding;
    }
    return $this->options['char_encoding'];
  } // function char_encoding

That should be:

  function char_encoding($char_encoding = NULL) {
    if ($char_encoding !== NULL) { // Error corrected
      $this->options['char_encoding'] = $char_encoding;
    }
    return $this->options['char_encoding'];
  } // function char_encoding

With both changes, accents should be not a problem for textile.module anymore.

There were two things going on here. First, the module did not specify utf-8 as the charset for the Textile class. Second, there was a bug in TextilePHP that caused it to ignore false values for char_encoding. This is all addressed in the latest files in CVS. The lastest version for both 4.5 and 4.6 should work properly.
