Hello!

When I launch GNU Emacs in an ISO Latin environment (env  
LC_CTYPE=de_DE.ISO8859-15 LANG=de_DE.ISO8859-15 /usr/local/bin/ 
emacs-23.1.50 -Q &) and display in dired a directory with entries  
from some month of March the "Mär" abbrevation for the German month  
name "März" is displayed as M\344r. C-u C-x = on this \344 reveals:

	        character: \344 (4194276, #o17777744, #x3fffe4)
	preferred charset: eight-bit (Raw bytes 128-255)
	       code point: 0xE4
	           syntax: w 	which means: word
	      buffer code: #xE4
	        file code: not encodable by coding system iso-latin-9-unix
	          display: no font available

The dired buffer has a 0 as encoding indicator. In ISO Latin 1 or 15  
encodings LATIN SMALL LETTER A WITH DIAERESIS is \344 = 228 = 0xE4 = U 
+00E4 a valid character and not some raw "eight-bit" entity. Could be  
this prevents proper display:

In *shell* buffer both Apple's ls and GNU's gls display:

Here the ä is described as:

	        character: ä (228, #o344, #xe4)
	preferred charset: iso-8859-15 (ISO/IEC 8859/15)
	       code point: 0xE4
	           syntax: w 	which means: word
	         category: .:Base, j:Japanese, l:Latin
	      buffer code: #xC3 #xA4
	        file code: #xE4 (encoded by coding system iso-latin-9-unix)
	          display: by this font (glyph code)
	    x:-b&h-lucidatypewriter-medium-r-normal-sans-10-100-75-75-m-60- 
iso10646-1 (#xE4)

The buffer's encoding is "0" as well, i.e., ISO Latin 1 or 15.

BTW, the issue is correct in UTF-8 environment.abbreviation

If you're not confused, you're not paying attention.

Hi,

I'm on the side of keeping the name of the coding-system to be 'utf-8-hfs',
as this coding system is defined by the specification of HFS+
(http://developer.apple.com/technotes/tn/tn1150.html), rather than
MacOS itself.   This implies that if other OS mounts HFS, they should
still apply "modified-NFD" for the file names.

Besides, the other components of MacOS handles UTF-8 as NFC, as seen
by the spotlight, etc.

It is very unfortunate (and possibly flaw) of Carbon API that they do not
care the file system they are accessing.  One must care by himself when
copying files among different file systems.  (For example, when I back-up
files among file systems with "rsync", I usually put some options such
as "--iconv=UTF8-MAC,UTF-8")... sigh....

Cheers,
