That's not actually a bug - that backslash-escaped character is the true
clipboard contents as sent by the VNC server.

If you try copying exactly "\u0107", or just a backslash, you'll find that
such strings are not escaped with yet more backslashes. Attempting to
decode such strings internally would be unsafe.

another bug / missing feature - some characters are not decoded in browser

1. instance 0.9.12 (outside docker, not hanging/spinning) is using
user-mapping.xml without any VNC clipboard encoding specified.
2. instance 0.9.13-RC1 (inside docker, hanging/spinning) is using
postgresql configuration with VNC encoding set to "UTF-8"

I'll try to disable "UTF-8" override. But if it's the case - I think
guacamole should be robust for that.


I agree - there's no doubt that would be a bug.

That said, overriding the clipboard encoding is guaranteed to violate the
VNC standard. Unless the VNC server itself is known to violate the standard
in the same way, that option should not be used.
