Comment (by majelbstoat):

 The recent addition of urldecode() also converts '+' to ' '.  This breaks
 plugins that have added custom permalink handling, that use '+' to
 separate arguments.  The specific case that broke for me is language
 appending in Gengo, which creates permalinks like site.com/en+de/ .  This
 gets decoded to site.com/en de/ which fails to match the regular
 expressions that have been set up.  I'm sure there must be other plugins
 out there which rely on this behaviour as well, as '+' is a very natural
 separator for specifying 'more than one'.

 I would request that rawurldecode() be used instead, which is identical to
 urldecode(), except that it preserves '+'.
