SDF File Format Version 3.1 Supports Class Names
With Non-ASCII7 Characters (NEW)
version is included in Map 2007 service packs.
The 3.1 file format can be read by 3.0 and 3.1
SDF providers, but 3.0 providers may not work correctly if the class
names contain such characters.
The SDF provider version 3.2.0 and above is
required to fully support non-ASCII7 characters set for class names.
