Hello SKHS,
Please find attached a re-write of the importexport util with a few quirks, including the fact that the exported data now goes to a file named based on its guid - so you don't have the problem related to the item name itself.
For additional information I recommand you run the tool with /? :D.
Note that this is a 7.5 build, and I'm not entirely sure whether it would work as-is on 7.6.
