Summary: utf-8 coding problem, kills weblinkchecker
Initial Comment:
Weblinkchecker chokes on many instances when reading the Special:Allpages of the ksh Wikipedia. It claims to see non-unicode data, which is unlikely to be so. I did not dig the code in detail atm, and I cannot tell the offending byte sequences atm.
Here is a copy of a linux command line, and the output generated by it:
$~> python weblinkchecker.py -putthrottle:300 -start:00er -v -family:wikipedia -lang:ksh
Checked for running processes. 1 processes currently running, including the current process.

Couldn't extract allpages special page. Make sure you're using MonoBook skin.
Saving history...
I had made sure, the user [[:ksh:User:Weblinkchcker]] was logged in, using the monobook skin, and the English interface language.
I could not make sure that weblinkchecker does use his user account while reading only. A test revealed that there is no apparent difference in behaviour when I rename login-data/wikipedia-ksh-Weblinkchecker-login.data to something else.
If there are questions, I am prepared to provide more info, once I know where to look.

The problem was that you found a very special case in Allpages, in which
you didn't get one single page of the kind you requested
(redirect/non-redirect), so you didn't get the next page but double-encoded
the current one. Fixed this in r4734. Note that the UTF-8 problem isn't
related to this bug (the "Couldn't extract allpages special page. Make sure
you're using MonoBook skin." message is related, and the problem was it was
a string, not a unicode, passed to wikipedia.output), but was fixed in
r4733.
