This is unrelated to UTF-8 but rather the various shells in play.

The default user interactive shell we use is zsh, but the default root
shell (except for the live CD) is /bin/sh, which is a symlink to dash
for some time now.

What's happening here is when you run "su", the prompt variable $PS1 is
being retained in the environment from your user's zsh session, and it
contains a bunch of zsh-specific escapes that dash doesn't understand,
so it just prints them literally (and thus the prompt looks really

Typically my advice is that you should always login as root using "su -"
instead of "su", the difference being the new shell will be run as a
"login shell" (/etc/profile and ~/.profile will be sourced) and the
environment will be cleared properly. You should then get a nice simple
"<hostname> #" prompt in that case from our default /etc/profile. This
is applicable to anywhere you use the "su" command to login as root, or
even as another user ("su - user" instead of "su user").
