Wikimedia Bugzilla is closed!

http://www.wikipedia.org/wiki/{{urlencode:Page Name}} returns http://www.wikipedia.org/wiki/Page+Name.

We need a function either
to get http://www.wikipedia.org/wiki/Page_Name 

or to replace 'space' to '_' in {{PAGENAME}} to get "Page_Name"

http://www.wikipedia.org/wiki/{{anchorencode:Page Name} return http://www.wikipedia.org/wiki/Page_Name. but it is not useful when we use Non-Latin PAGENAME. it converts '%' to '.' too.

please see https://bugzilla.wikimedia.org/show_bug.cgi?id=7059 and https://bugzilla.wikimedia.org/show_bug.cgi?id=839 for more information.

We face this problem in http://ml.wikipedia.org/wiki/Template:Sarvavijnanakosam. Its not possible to make a link to other wiki article if Page Name contain Non-Latin character with space. Example: An article in Malayalam Wikipedia (http://ml.wikipedia.org/wiki/തൊപ്പിക്കാരൻ_കുരങ്ങ്) required link to similar article in Sarvavijnanakosam (http://mal.sarva.gov.in/index.php/തൊപ്പിക്കാരന്‍_കുരങ്ങ്)
