Hi Sorry for my English :) What I need is case insensitive titles. My solution for the problem was tochange collation in mysql from <unf8_bin> to <utf8_general_ci> in table<page>, for field <page_title>. But bigger problem with links persists. In my case, if there is an article<Frank Dreben>, link [[Frank Dreben]] is treated like a link to an existentarticle (GoodLink), but link [[frank dreben]] is treated like a link to anon-existent article, so, this link opens editing of existent article <FrankDreben>. What can be fixed for that link [[frank dreben]] to be treated likea GoodLink? I've spent some time in Parser.php, LinkCache.php, Title.php, Linker.php,LinkBatch.php but found nothing useful. The last thing I tried was to dostrtoupper on title every time array of link cache is filled, inLinkCache.php. I also tried to do strtoupper on title every time data isfetched from the array.I've tried to make titles in cache be case insensitive, but it didn't workout, not sure why - it seems like when links are constructed (parser, title,linker, etc) only LinkCache methods are used. Could anybody point a direction to dig in? :)
