20399,WordPress removing multiple dashes/hyphens breaks my permalinks,colinwiseman,,"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.",defect (bug),closed,normal,,General,3.3.1,normal,invalid,,
