asynmetric escaping of url for wiki page name

[Shunichi Goto <gotoh@…>]

I upgaraded from trunk r2947 to r3008 today, and I've encounted problem around url escape. It seems that page name is not un-escaped from url.

To reproduce:

1. Go to ​http://projects.edgewall.com/trac/wiki/%E6%BC%A2%E5%AD%97
   This URL means non-existant page whose name is "漢字" (japanese character). The utf-8 code of this page is E6 BC A2 E5 AD 97. At this point, this empty page should contains a text Describe "漢字" here. but r3008 shows us as Describe "%E6%BC%A2%E5%AD%97" here. This is wrong.
   2. Then on pressing "Create this page" button, the url is changed to %25E6%25BC%25A2%25E5%25AD%2597. Apparently it is double escaping. And it happens more and more by pressing preview buttons.

Thus we cannot create new and edit existing non-ascii page correctly.

I think it's a duplicate of #2864. Can you try the fix I posted there?

Bingo! The problem has gone. Thanks.

I'd still be interested in knowing what front-end you're using ;-)
