invalid characters for ISO-8859-1 response

If I do the docbook -> xhtml transformation (v 4.4) I get invalid
characters for the chapter numbers in the output. If I change the
character encoding in the browser view from ISO-8859-1 to UTF-8 they
look ok.

I have to use ISO-8859-1 for now, because that's what the server sends
the response as...also, I'm unclear why there are special characters
at all in the output just to display chapter numbers:

output:
<h2 class="title"><a id="reports"></a>Chapter?| 3.?| Reports</h2>

Note the "Chapter?|3.?|Reports" (this is from vim when I view the
source directly, I get the "A-hat" character when viewing source in
the browser.

How should I fix this problem, all I really need is a space..no
special character to represent "Chapter 3. Reports" should be needed
here.

I tried changing the xml charset in the xml declaration, but that
didn't do anything.
