What is the value of PS1 before you prepend ampersand-hash-space to it?

What does the ampersand-hash-space have to do with the problem?

Who's "you"?  Aren't you, Thomas, the person having the problem?

At first glance this looks like the classic "I have colors in my prompt
and I forgot to put \[ \] in the right places", but it's hard to be sure
because the description is so confusing.

In what locale?  UTF-8, ISO-8859-1, or what?  Is the accented character
a single-byte character, or a multi-byte character, in your locale?

I did this in an ISO-8859-1 locale and did not reproduce the problem.

Then I did it on a UTF-8 locale (differet computer) and also did not
reproduce the problem.  Granted, I'm controlling the UTF-8 X session
from the mouse and keyboard that are on the ISO-8859-1 machine, but
od -t x1 tells me that the file name I created on the UTF-8 machine
has a multi-byte character in it, so I'm not sure what is required
to reproduce the issue.
