From 79d86829294ac54132c01153660e70e30c15c378 Mon Sep 17 00:00:00 2001
From: Jeff Mitchell <mitchell@kde.org>
Date: Wed, 22 Sep 2010 18:15:17 -0400
Subject: [PATCH] Re-add some tests for unprintable but also invalid chars. Apparently Qt's XML classes don't properly check for invalid chars when writing XML, even if you tell them to.
Also switch to QXmlStreamWriter, as apparently going forward it is the more supported class.
BUG: 251762
