Forwarded bug from Ubuntu. ----- Binary package hint: mediawiki mediawiki blocked %[a-f][a-f] only, that's confusing if these names will lead to problems, you'd better block "%" entirely for better understanding. and i don't know what are the problems. it doesn't appears to be any problems since all links to the name "%ft%rs" works well. if there are, those should be bugs. if these names will not lead to problems, why should you have such a limit? remove it.
http://en.wikipedia.org/w/index.php?title=%AB&redirect=no seems to work fine.
http://www.mediawiki.org/wiki/%ab - works, though because it's not valid UTF-8 it gets converted to « according to content language's fallback encoding. http://www.mediawiki.org/wiki/%ft - "Bad Request" by Apache http://www.mediawiki.org/w/index.php?title=%ft - works, though because %ft is not a valid URL-encoded sequence, it gets eventually converted to %25ft same thing with %a I see no problem with MediaWiki, just Apache/rewrite rules.
Aforementioned bug: https://bugs.launchpad.net/ubuntu/+source/mediawiki/+bug/577822
This is the correct behavior, since we only block "%[0-9A-Fa-f]{2}" to not conflict with URL escaping sequences (includes/Title.php line 2420 in trunk).
So to clarify, this behaviour is by design? Is it likely to be left like that or changed in future?
This behaviour is by design indeed.
