From 81ba16cad933981f55218964a89ed1446022efba Mon Sep 17 00:00:00 2001 From: Lars Knoll Date: Mon, 24 Mar 2014 16:12:20 +0100 Subject: Fix case insensitive comparisons using QCollator In ICU the strength parameter decides whether a comparison is case sensitive or not. Fix mac comparison code. It can't have worked before. Added some basic automated testing for QCollator.
