We can't just add a `u_charType(ch) == U_CONTROL_CHAR` stanza to ComplexTextController::adjustGlyphsAndAdvances(), because that iterates over glyphs, and Core Text doesn't give us a glyph for this character at all, so we don't encounter anything to fix up.

After discussing with the Core Text team, we think we're going to focus on just deleting the complex text codepath (in favor of the fast text codepath), instead of trying to fix this bug in the complex text codepath.
