• Describe the scenario and benefits that the feature supports.

CompareStringOrdinal() is a "new" (to Vista) function that compares string non-linguistically. As the doc calls "examples of such non-linguistic strings are NTFS file names, environment variables, and the names of mutexes, named pipes, or mailslots".

• Describe how you're accomplishing the feature today (if possible).

Much of the WiX native code uses CompareString(LOCALE_INVARIANT because the code was designed to support XPSP2.

• Describe what you'd like the new feature to do.

Given that WiX requires at least Win7, we should evaluate each use of CompareString(LOCALE_INVARIANT and whether it should use CompareStringOrdinal() instead.
