@Blujely – The DOMVersion number refers to the InDesign version number (in your case v8, InDesign CS6 or its CC equivalent).
A quick test in my InDesign CS5.5 v7.5.3 on Mac OSX 10.6.8 in this regard was showing no problem at all. DOMVersion 7.5.
I cannot test it right now with CS6, but we have to make sure, if the problem is
either:
1. At the sender's side (the export module – IDML Export or IDMS Export of InDesign)
or:
2. At the side of the reciever, could be InDesign's importing module or a 3rd party tool like a Translation Memory Software like Trados.
To check the sender's side:
If you have that Story_xxxx.xml file open, could you detect the wrong character already there? Search for a unique word near the problem character you have seen on the reciever's side.
What exact version of InDesign are you using to export the IDML/IDMS?
In InDesign go to the menu "About InDesign" and look after something like version 8.0.0 or 8.0.1 or 8.0.2 (the latest bug-fix version).
What software is showing the problem when you import/place/open the IDML/IDMS?
