Michael Jumper commented on GUACAMOLE-265:
------------------------------------------
OSC 0 as a means of setting the window title is part of the set of console
codes supported by xterm (and tools which support those same codes, like the
Gnome or MATE terminals). Guacamole's terminal emulator currently implements
the same subset of console codes as the Linux console, not xterm.
Adding such support would be nice, but this is not a bug.

> Key: GUACAMOLE-265
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-265
> Project: Guacamole
> Issue Type: Bug
> Components: SSH
> Affects Versions: 0.9.12-incubating
> Reporter: Mark Tomich
> Priority: Minor
>
> The easiest way to test this is to manually change the window's title. For
> example, the following command works to change the window's title when using
> gnome-terminal:
> {code:none}
> $ PROMPT_COMMAND='echo -ne "\033]0;SOME TITLE HERE\007"'
> $
> $
> {code}
> When this same command is run through Guacamole, part of the new title is
> printed inline on every line (everything save for the first alphabetical
> character), and resembles artifacting:
> {code:none}
> $ PROMPT_COMMAND='echo -ne "\033]0;SOME TITLE HERE\007"'
> OME TITLE HERE $
> OME TITLE HERE $
> {code}
> ...NB: if you run this same command inside gnu screen, the output is slightly
> different (note the subsequent command prompts lack the same title
> artifacting)
> {code:none}
> $ PROMPT_COMMAND='echo -ne "\033]0;SOME TITLE HERE\007"'
> OME TITLE HERE $
> $
> {code}
> ...furthermore, if you detach and reattach to the same gnu screen, the
> artifacting is gone.
