 As of Wordpress 4.5, any query strings using a "." will get converted to a
 "_". While i understand that PHP doesn't support a period in a query
 string value, there are instances where query strings with periods are
 used by JavaScript  and need to be retained. For example, the Webtrends
 analytics platform uses periods in most of their analytics query string
 values. For example, they use "wt.mc_id", "wt.z_mce", and "wt.dl".

 It appears that changes to 'wp-includes/canonical.php' in 4.5 cause these
 periods to be visually and functionally converted to underscores when the
 pages loads. Interestingly, this only happens on pages and not posts.

 Can we get the functionality put back the way it was so that the periods
 are retained, as this update will break Webtrends functionality, as well
 as any site using JavaScript that expects a period in a query string
 value?
