Re: bash strangeness with utf-8

[Giraud]

Hmm, interesting.  I thought that using "env | grep PROM" would show
PROMPT_COMMAND's value, but I guess not.  Yes, I do have PROMPT_COMMAND
set, it appears.  However, if I unset it (and even also 'export PS1="foo
"' to set PS1 to a simple string), the problem remains.

How best to debug this?  tcsh and sh do not exhibit the problem, and it
only seems to happen on Gentoo/FreeBSD (not Linux).
