Here is a small change I made to convert foreign characters to their English equivalent.
Create My_url_helper.php and place in application/helpers/ folder. Next add this code:
Code: <?php if (!defined('BASEPATH')) exit('No direct script access allowed');
// ------------------------------------------------------------------------
/**
* Create URL Title
*
* Takes a "title" string as input and creates a
* human-friendly URL string with either a dash
* or an underscore as the word separator.
*
* @access public
* @param string the string
* @param string the separator: dash, or underscore
* @return string
*/
if (! function_exists('url_title'))
{
function url_title($str, $separator = 'dash')
{
if ($separator == 'dash')
{
$search = '_';
$replace = '-';
}
else
{
$search = '-';
$replace = '_';
}
$str = convert_accented_characters($str);
$trans = array(
$search => $replace,
"\s+" => $replace,
"[^a-z0-9".$replace."]" => '',
$replace."+" => $replace,
$replace."$" => '',
"^".$replace => ''
);
$str = strip_tags(strtolower($str));
foreach ($trans as $key => $val)
{
$str = preg_replace("#".$key."#", $val, $str);
}
return trim(stripslashes($str));
}
}
// ------------------------------------------------------------------------
/**
* Convert Special Chars
*
* Found Via:
* http://us.php.net/manual/en/function.chr.php#72145
*
* @access public
* @param string the string
* @return string
*/
function convert_accented_characters($string)
{
for ($i=0;$i<strlen($string);$i++)
{
$chr = $string{$i};
$ord = ord($chr);
if ($ord>32 and $ord<126 or $ord==195)
continue;
elseif ($ord==161 or $ord>191 and $ord<198)
$string{$i} = 'a';
elseif ($ord==169 or $ord>199 and $ord<204)
$string{$i} = 'e';
elseif ($ord>203 and $ord<208)
$string{$i} = 'i';
elseif ($ord>209 and $ord<215)
$string{$i} = 'o';
elseif ($ord>216 and $ord<221)
$string{$i} = 'u';
elseif ($ord>223 and $ord<230)
$string{$i} = 'a';
elseif ($ord>231 and $ord<236)
$string{$i} = 'e';
elseif ($ord>235 and $ord<240)
$string{$i} = 'i';
elseif ($ord>241 and $ord<247)
$string{$i} = 'o';
elseif ($ord>249 and $ord<253)
$string{$i} = 'u';
elseif ($ord>252 and $ord<256)
$string{$i} = 'y';
elseif ($ord==241)
$string{$i} = 'n';
elseif ($ord==209)
$string{$i} = 'N';
else
$string{$i} = '';
}
return $string;
}
?>
This will hopefully convert á=a, é=e, etc. If anyone sees any problems or improvements please pass them along.

Thanks! Going to try it out.

Slight issue. It is seems to change spaces into something and when url_title comes in it will remove it.
So something like url_title('this is a test') becomes 'thisisatest' instead of 'this-is-a-test'

Found another code snippet on the web that might work...
function convert_accented_characters($string)
{
return strtr($string,
"ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝßàáâãäåæçèéêëìíîïðñòóôõöøùúûüýÿ",
"SOZsozYYuAAAAAAACEEEEIIIIDNOOOOOOUUUUYsaaaaaaaceeeeiiiionoooooouuuuyy");
}

Oops. That last line:
Code: else
$string{$i} = '';
Should be:
Code: else
$string{$i} = ' ';

The only one that worked for me on a win7 wampserver.
Code: function convert_accented_characters($string) {
return strtr($string,array(
'Š'=>'S', 'š'=>'s', 'Đ'=>'Dj', 'đ'=>'dj', 'Ž'=>'Z', 'ž'=>'z', 'Č'=>'C', 'č'=>'c', 'Ć'=>'C', 'ć'=>'c',
'À'=>'A', 'Á'=>'A', 'Â'=>'A', 'Ã'=>'A', 'Ä'=>'A', 'Å'=>'A', 'Æ'=>'A', 'Ç'=>'C', 'È'=>'E', 'É'=>'E',
'Ê'=>'E', 'Ë'=>'E', 'Ì'=>'I', 'Í'=>'I', 'Î'=>'I', 'Ï'=>'I', 'Ñ'=>'N', 'Ò'=>'O', 'Ó'=>'O', 'Ô'=>'O',
'Õ'=>'O', 'Ö'=>'O', 'Ø'=>'O', 'Ù'=>'U', 'Ú'=>'U', 'Û'=>'U', 'Ü'=>'U', 'Ý'=>'Y', 'Þ'=>'B', 'ß'=>'Ss',

I made some modifications so you can chose to transform the text into lowercase or not.
And I added "space" as a separator to perform a JavaScript search (just a thing I needed to do).
Brazilian Portuguese
Com essa função você transformará todos as letras acentuadas em letras não acentuadas. Exemplo: "Não faça pão" retornaria "Nao faca pao".
Modifiquei a função para que ela permitisse escolher entre todas as letras minúsculas ou não. E adicionei a opção de separar as palavras com espaço (precisava para uma pesquisa em JavaScript).
Code: <?php if (!defined('BASEPATH')) exit('No direct script access allowed');

Thanks! Small and good contribution. I'll try it later. ;-)
[eluser]rip_pit[/eluser]
thank you! seems to work fine with the few tests I did

Almino Melo. 
I extended your code because the hungarian characters were missing from your array.
Add these lines to work with hungarian characters:
Code: return strtr($string,array(
[...]
'ő' => 'o',
'Ő' => 'O',
'ü' => 'u',
'Ü' => 'U',
'ű' => 'u',
'Ű' => 'u'));
