From e8199b599f6c6a438365afb10a00ec8af5ae7243 Mon Sep 17 00:00:00 2001 From: Konstantin Ritt Date: Fri, 11 May 2012 14:19:44 +0300 Subject: QChar: add missing UCS-4 overloads, get rid of UCS-2 ones inline all non-static members to a static ones (declared with QT_FASTCALL), ushort converts automatically to uint and the conversion cost is minimal.
