url_title and apostrophe

I noticed that the url_title fonction does not convert apostrophes (single quotes) to dash (or underscore).

French apostrophe is the same character as single quote.
For example : "L'apostrophe" should be slugifyed as "l-apostrophe"
Currently, single quotes are removed and not converted to separators (L'apostrophe → lapostrophe).

I would like to update the url_title function, but I'm not familiar with regex. Could someone help me to update the function so that it converts single quotes into dash.

PHP Code:

// url_helper.php - line 493
$trans = array(
 '&.+?;' => '',
'[^\w\d _-]' => '',
'\s+' => $separator,
'('.$q_separator.')+' => $separator
); 


URL Helper ain't an expert on foreign characters, but convert_accented_characters() are.
url_title(convert_accented_characters('L'apostrophe'));

Can't seem to find it, so you need to add it in your application/config/foreign_chars.php
'/L\'/' => 'L-',

That's interesting. The problem is that, in French, apostrophe can be associated to many characters, for example :

• Aujourd'hui
  
• D'avantage
  
• L'amérique
  
• N'ai-je donc 
  
• Ch'ti
  

Not sure this is a good idea to add the following line in foreign_chars.php

PHP Code:

'/\'/' => ' ', 


What do you think ?

No, not really.

I would make a function like this:

PHP Code:

function french_url_title($str,$seperator='-',$lowercase=FALSE) {
    url_title(str_replace("'",'-',$str),$seperator,$lowercase);
}
