Support comma in subtitle string when (not json)

[martinvandiemen]

Is your feature request related to a problem? Please describe. The new subtitle is great but it doesn't support comma like progress text does. It will break the line remove the part starting from the comma. We need to be able to append the string to the command file instead of the JSON (because of the workflow we have).

Describe the solution you'd like Support comma like in progress text.

Describe alternatives you've considered I tried a fullwidth comma but this isn't passed through to the client correctly.
