Hmmm.

The problem isn't that the RegionPersonDisplayName is a simple string.

The problem is that one of the equals signs is getting eaten somehow.  That I don't understand.  Why is there only one "=" separating the names?  Try other separators to see if they work.  Could Windows be somehow changing the "==" command-line argument to "="?  What is the output of echo "=="?

Somehow Windows must be eating one of the = symbols.  Bad luck on my part to choose this symbol I guess.

The echo command didn't help, because somehow it seems to be bypassing normal argument parsing (since the quotes show up in the output).

I did some googling, and the equals sign is a delimiter for Windows .BAT file arguments.  Somehow this seems to be affecting us here.  But this doesn't make sense because lots of other ExifTool arguments with equals signs work fine.  (ie. -artist=phil)

I'll see if I can remember to play around with this the next time I am on a Windows machine.
