REST API treats URL encoded forward slash as a slash

Changing status to Confirmed, server is OOPSing on such filenames, google map icons for instance. I'll probably fix this on the client side replacing % with _, but that's just temporary fix, it's not the client fault that a filename may contain URL encoded characters. Stuart Langridge said it's clearly a bug.
