MRCPRecog fails to parse grammar url because it contains a JSON payload.

[sombat-net]

Hi guys.
It's possible that the grammar url contains a json payload; I'm trying, but MRCPRecog application sends the wrong grammar url (comma sepalator issue).

example grammar url.
builtin:speech/transcribe?method=Execute;user-id=1234;model-uri=urn:nuance-mix:tag:model/xxxxxx/mix.dialog;selector-channel=IVRchannel;language=th-TH;start-request-payload-json={"selector":{"channel":"IVRchannel","language":"th-TH","library":"default"},"payload":{"data":{"userData":{"timezone":"America/Cancun","userGlobalID":"123123123","userChannelID":"163.128.3.254","userAuxiliaryID":"7319434000843499","systemID":"4561 9219 9923","location":{"latitude":"21.161908","longitude":"-86.8515279"}},"preferred_coffee":"espresso","user_name":"Miranda"}}}

Erro logs.

Thank you.

Hi @sombat-net

You would need to escape double quotes in the JSON data to allow MRCPRecog to properly parse the arguments. For example

{\"selector\":{\"channel\"
