Apparently the Win7 CLI does not strip single quotes from arguments, making the JSON string invalid. The following works.

Code:

--display="{\"date_format\":\"MM/dd/yy\"}"

while this doesn't:

Code:

--display='{\"date_format\":\"MM/dd/yy\"}'

Putting print statements in the code, we see that the first arrives in calibre as

Code:

{"date_format":"MM/dd/yy"}

while the second second arrives as

Code:

'{"date_format":"MM/dd/yy"}'

(note the single quotes).

So, the solution for Win7 is to use double quotes and escape all internal quotes.
