Page title validation #38
Description
I have no idea how the $wgLegalTitleChars are applied in MediaWiki. It works with ASCII titles, but not with Unicode - the default value contains far too few characters that are actually enabled. I tried to fix this in be47de2 but that's not enough, since Unicode punctuation characters are not enabled yet.
Percent encoding or HTML entities are out of question too, they are explicitly disabled in the getTitleInvalidRegex function.
