[b.riefenstahl@turtle-trading.net: Mac: set-language-environment trashes default-file-name-coding-system]

[Richard Stallman]

Would someone please DTRT?

Maybe it would be better on MacOS to ignore
default-file-name-coding-system and alays use `utf-8'.  Or maybe
reset-language-environment should avoid setting that variable.

Hi all,

- - Start Emacs as emacs -q. 
- - default-file-name-coding-system is set to `utf-8'. 
- - M-x set-language-environment RET UTF-8 RET. 
- - default-file-name-coding-system is now set to `iso-latin-1' (!). 

On Mac OS X the encoding of filenames is always UTF-8.

The problem occurs in the implementation of set-language-environment
in mule-cmds.el.  set-language-environment calls
reset-language-environment which sets default-file-name-coding-system
to iso-latin-1 unconditionally.  After that, set-language-environment
calls set-default-coding-systems but that function avoids setting
default-file-name-coding-system specifically on Darwin/Mac OS X.

Instead, I've just installed this change because it seems
simplest.

	set default-file-name-coding-system to utf-8 for Mac Darwin.
