Alternate unaccent function implementation

This is not really a feature request, but rather just a heads up for a possibly simpler method for downgrading accented characters into their non-accented versions.

Specifically, I'm referring to the unaccent() function from http://bendiken.net/snippets/php

function unaccent($text) {
  static $search, $replace;
  if (!$search) {
    $search = $replace = array();
    // Get the HTML entities table into an array
    $trans = get_html_translation_table(HTML_ENTITIES);
    // Go through the entity mappings one-by-one
    foreach ($trans as $literal => $entity) {
      // Make sure we don't process any other characters
      // such as fractions, quotes etc:
      if (ord($literal) >= 192) {
        // Get the accented form of the letter
        $search[] = $literal;
        // Get e.g. 'E' from the string '&Eacute'
        $replace[] = $entity[1];
      }
    }
  }
  return str_replace($search, $replace, $text);
}

Not sure if this method can be of use to you, but wanted to ensure awareness of its existence.
