Description:
http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&fulltext=Search&ns0=1&redirs=1&search=intitle: (append one UTF-8 character) does not show redirects if the character searched has code point above U+007F. en.wikipedia.org/wiki/Special:Search/intitle: even does not show articles (non-redirect pages) for some code points. Apparently the bulk of this bug affects only en.wiki. Examples:
http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%C2%85&fulltext=Search&ns0=1&redirs=1&profile=advanced – but U+0085 NEL (non-graphic) redirect exists: http://en.wikipedia.org/wiki/%C2%85
http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%C2%A2&fulltext=Search&ns0=1&redirs=1&profile=advanced – but the [[¢]] redirect exists: http://en.wikipedia.org/wiki/%C2%A2
Note: I was unable to locate any wiki where intitle:¢ for U+00A2 gives some results, which means that in other wikis something is broken too
http://en.wikipedia.org/w/index.php?title=Special%3ASearch&profile=advanced&search=intitle%3A%CF%B7&fulltext=Search&ns0=1&redirs=1&profile=advanced – but the [[Ϸ]] redirect exists: http://en.wikipedia.org/wiki/%CF%B7
