You describe your example as a single line, but it has 3 lines. What does it really look like? What are the "3D"s doing in there? If this is XML, their presence makes it invalid.
Please show us precisely an original line, and precisely what you want it changed to.
I don't think the reason the "3D" is in the string has anything to do with the question I asked. This is an mht file generated by a MS Office document. I don't know why it's there - and don't really care.
