Sorry, this is no mac-roman, it's exactly what I see in xterm or in 
Terminal in the shell buffer -- although I should see something 
different: äöüßÜÖÄ€. That's the file's name. (Mail.app claims that it 
is using a 7bit encoding.)

My .emacs file is only 8bit, so I chose ISO Latin-15. In its header it 
is explicitly written

;;; -*- mode: Emacs-Lisp; coding: iso-8859-15; -*-

When I copy a string with characters from this set via double-clicking 
the selection and paste it either in the same or in the (Unicode) 
scratch buffer the simple accented chars become each a series of this 
character and mostly \216 -- me and others have seen similiar things in 
GNOME under Linux when copying from outside GNU Emacs. Pressing umlauts 
etc. on my keyboard enter exactly these umlauts into the buffers. C-x = 
explains in hex that they're taken from the usual code positions (for 
example Ä is 0x8c4, ä is 0x8e4).

I can send you a snapshot privately ...

There is no char. So there should not be a box. The correct string is 
äöüß... and as it's a file name, it's UTF-8 encoded. (Since the 
displayed glyphs are the chars stripped off their diaeresis the box 
could be ... but it's : "(01211310, 332488, 0x512c8, file ...). A bit 
astronomical high. æ and Æ and € are represented by themselves.

Since the Fink team decided to distribute in the unstable section an 
Emacs from CVS ... (but there was not much difference to 21.3.50, it 
might be exactly 0 in this case)
