As I said, if all the following evaluate true:
'''
                if( (pCur->FontId == pNext->FontId || isSpaces(pNext)) &&
                    rCurGC.FillColor.Red == rNextGC.FillColor.Red &&
                    rCurGC.FillColor.Green == rNextGC.FillColor.Green &&
                    rCurGC.FillColor.Blue == rNextGC.FillColor.Blue &&
                    rCurGC.FillColor.Alpha == rNextGC.FillColor.Alpha &&
                    (rCurGC.Transformation == rNextGC.Transformation ||
notTransformed(rNextGC))
                    )

then the chharacters will be combined into strings and then the mirror code
would be triggered which will reverse the reversed char sequence, thus produce
correct ones in the XML. 

So the issue now is how to modify the last condition "(rCurGC.Transformation ==
rNextGC.Transformation || notTransformed(rNextGC))" to correctly detect the
current char is of the same transformation thus they should be combined into
string.
