 Recently been trying to upgrade to WordPress 3.3.1 but a lot of our
 writers use characters like ~ and " in their titles, which am fine with as
 WordPress has always changed these to dashes.  So our URLs have multiple
 dashes/hyphens.

 I have tracked this down to line 892 of /wp-includes/formatting.php which
 is:

 `$title = preg_replace('|-+|', '-', $title);`

 and so it replaces more than 1 consecutive occurance of - with a single -.
 And this is as the point the code checks the database.  Thus a URL e.g.
 "colin---wiseman---2012" gets changed to "colin-wiseman-2012" which is not
 a name of a post in the database.

 We cannot go back and change all our URLs as there are 1000s of pages and
 linked to from all around the internet.

 The only solution I have found is to comment out this line, but I'd rather
 there be an option in WordPress that I can flag in the wp-config e.g.
 define("SANATIZE_DASHES", false); so that the next time I upgrade
 wordpress there isn't this issue.

 I feel that until then, this is a serious bug that could be affecting more
 blogs than just mine.
