WKCreateCTLineWithUniCharProvider is a wrapper around Core Text private API. It does the same thing that the public function CTLineCreateWithAttributedString does, except that instead of taking an attributed string as a parameter, it takes a pointer to a callback function that returns runs of characters and attributes. Core Text source code is not published.
