Ralf,
The problem, I believe, is that the DOS command parser does not understand
backslash escaping to protect the internal double quotes. I don't really
know if the above can be processed properly by the DOS command parser.
One option might be to install Cygwin which provides a unix-like shell
interpreter (bash) that should follow normal unix rules.
Alternatively, you could possibly invoke os.execl() in python to invoke
a subproject with preparsed arguments.
I had wanted to suggest using the GDAL/OGR --optfile switch which allows
reading command options from a text file, but on review I think the
escaped quotes will also end up confusing it and you will be no better off.
Best regards,
--
