buff-menu.el in CVS today has utf-8 characters?

[Drew Adams]

I create a new buffer foo.el, and paste the text from buff-menu.el
(from CVS) into it. When I try to save, I get this message:

These default coding systems were tried to encode text
in the buffer `buff-menu-CVS-2005-06-14.el':
  undecided-unix iso-latin-1
However, each of them encountered these problematic characters:
  undecided-unix: ⠀ “ ⠀ ” ⠀ ”
  iso-latin-1: € “ € ” € ”
The first problematic character is at point in the displayed buffer,
and C-u C-x = will give information about it.

Select one of the following safe coding systems, or edit the buffer:
  utf-8 windows-1258 windows-1256 windows-1254 windows-1250 mac-roman
  windows-1252 utf-16 utf-16 utf-16 utf-16be utf-16le iso-2022-7bit
Or specify any other coding system
at the risk of losing the problematic characters.

In the minibuffer, it says "Select coding system (default mule-utf-8):"

Point is on this in buff-menu.el: –-Stef

Questions:
Is it normal to have these characters in the file?
Does this file need to be utf-8? Should it be?
What coding system should I use to save this file? I used utf-8.

The first line of the buffer has this - shouldn't it force utf-8
encoding automatically?  -*- coding:utf-8 -*-
