[BUG] First tilde removed in any message

[Blenderplayer]

Describe the bug
First tilde removed in any message in JSON Channel

To Reproduce

1. Create a Channel with JSON Datatype input
2. Write any message with at least one ~ (e.g. { a: 'afirstinput', b: 'asecondinput' } )
3. Go to Channel Scripts => Preprocessor and log the message
4. The example message is displayed without the first ~ ( { a: 'afirstinput', b: 'asecond~input' } )

Expected behavior
The message should keep all tilde characters, as it isn't a HL7 message

Actual behavior
The first occurence of a tilde character is removed

Screenshots

Additional context
We need the tilde character for intern Api calls, that pings a REST API endpoint.

cannot replicate that. You sure you do not have a global preprocssor? If this was a bug it would break dozens of my channels that get HL7 messages in raw format encapsulated in JSON.
