This bug is about redirects using %nn characters as you can see at
http://en.wikipedia.org/w/index.php?title=User:Gangleri/tests/bugzilla/00927/%2C&action=edit

This will *fail*:
#REDIRECT [[Winston-Salem%2C_North_Carolina]] {{R from misspelling}}

This is *OK*
#REDIRECT [[Winston-Salem,_North_Carolina]] {{R from misspelling}}

http://en.wikipedia.org/w/index.php?title=User:Gangleri/tests/bugzilla/00927/%D7%90%D6%B7&oldid=38759916
*fails* because of
Bug 1527: *first* perform Unicode normalisation and check for existence of pages
*after* the normalisation

REOPENing bug

It's another junk page with multiple paragraphs of drivel on it.
Please create minimal, standalone test cases that test *only*
the thing you're trying to get us to look at. Having to tear
through a jungle or irrelevant junk text is extremely time
consuming; you file a lot of these things and it would be very
helpful if you could keep each one small and relevant.

Hallo Brion!

Please go and edit

Please replace "%2C" with ",". This will "fix" the redirect.

*request*
The target link should be normalised. Then the existence should be checked. Then
the special "REDIRECT rendering" should be applied.

Test case:

Create a page ''Bug4917'' containing:

• [[Bug4917/redirect]]
• [[Bug4917,thebug]]

Edit [[Bug4917,thebug]] and enter some text.

Edit [[Bug4917/redirect]] and enter:
#REDIRECT [[Bug4917%2Cthebug]]

Save and go to [[Bug4917]], clicking on [[Bug4917/redirect]] show the page
but redirect is not followed.

% is a valid title character. There is a double-unescaping bug in apache which
may occasionally make it appear as if %2C is a valid substitute for "," in link
syntax, but it is not. %2C means %2C.

Percent codes are decoded in inline wikilinks (in part for backwards-compatibility
with interlanguage links from the olden days).

% is a valid title character, but %[0-9a-f]{2} is blacklisted to prevent
unreachable titles.

Seems to have been fixed some time ago.
