Square Brackets stripped out of Messages

I have an emailer device which uses an edited version of the DoNS-Email driver. I send messages to it using a trigger in RM with a Notify action. The only change I made was to check if the message is wrapped in square brackets ([ ]) then replace with curly brackets ({ }) to signify json. That is because in RM 2.5, curly brackets have a special meaning.

Now it seems that in RM 3.0, square brackets are stripped out of messages. Is this intentional? now my emailer doesn't recognize the json. Any suggestions on passing json in a message? I'm trying to use angle brackets (< >) with a replace to curly brackets, but that is not working either.

I believe this will be fixed in an upcoming feature release. I remember reading something about this.

Ok, Thanks.
