JSON string commands do not appear to be parsed as JSON strings

[tryashtar]

Using unicode escapes in JSON commands (queue_command, on_open_commands) simply prevents the command from parsing, including reporting errors.

All three of these commands are identical strings after parsing, so should produce the same result.

Don't think I can solve this one, the JSON parsing used is just plain JS JSON parsing, and I have to look up where in the text the problem is to find where it is, The unicode codes get synthesised into normal text and thus I cannot do a lookup back where it is
