There's even a JSON mode.
By miracle, would the JSON output mode recognize JSON[B] values, and avoid the escaping?

I agree there should be a copy option for “not formatted” so if you dump a single column result in that format you get the raw unescaped contents of the column. As soon as you ask for a format your json is now embedded so it is a value within another format and any structural aspects of the wrapper present in the json text representation need to be escaped.

Is it better to use the LO API for this purpose?  It is native for not formatted data.
