Ah, yes, the MHD PostProcessor does not support 'all' possible
encoding types. If your client sends an unsupported encoding,
you need to parse "*upload_data" yourself.  Note that the
MHD_PostProcessor only exists for convenience, you could write that
entire logic as a client.  So please simply look at what the PP does for
the supported encodings, and then write a 'custom' PP for JSON.

Happy hacking!
