I am visiting South Africa, and I heard a complaint here that in some languages that are spoken here article titles are often supposed to begin with a lowercase letter, but they are forced to an uppercase letter. An example is the article IBhayi in the Xhosa Wikipedia, which appears as "IBhayi", but is supposed to appear as "iBhayi".
Maybe it can be solved by setting $wgCapitalLinks to true, maybe by frequent use of DISPLAYTITLE on the projects, and maybe by something else.
I'll update the ticket when I learn more details about the requirements, but anybody who knows these languages well is welcome to suggest anything.
