set-language-environment

[Peter Dyballa]

Hello!

Setting this value to German executes line #2170 in mule-cmds.el:

     ("de" "German" iso-8859-1)

Since almost one decade we live in the Euro zone. Iso-8859-1 is  
completely wrong, iso-8859-15 is the right choice in the 8 bit encoding.

Look, here is a map of those countries that have the € as their local  
currency: http://www.ecb.de/bc/intro/html/map.en.html. In the next  
years more will follow.

I don't think so.  "de" is iso-8859-1.  "de@euro" is iso-8859-15.  The
problem is rather that we don't have the "@euro" correspondes in the
file.

Does not change the locale definitions magically.  Here are the
entries for "de" from /usr/share/i18/SUPPORTED on my system:

de_AT.UTF-8 UTF-8
de_AT ISO-8859-1
de_AT@euro ISO-8859-15
de_BE.UTF-8 UTF-8
de_BE ISO-8859-1
de_BE@euro ISO-8859-15
de_CH.UTF-8 UTF-8
de_CH ISO-8859-1
de_DE.UTF-8 UTF-8
de_DE ISO-8859-1
de_DE@euro ISO-8859-15
de_LU.UTF-8 UTF-8
de_LU ISO-8859-1
de_LU@euro ISO-8859-15

Oops, upon closer looking, we do have the "@euro" stuff treated there.

So I guess you are just wrong.

Yes.

?? When you run Emacs as this:
% LANG=de_DE@euro emacs

Emacs is in German language environment and the default
coding system is set to iso-8859-15.

Having in .emacs

	(set-language-environment       'German)

*scratch*, *Messages*, *mail*, dired buffers ... have a modeline  
starting with

	-1:

which does not stand for ISO 8859-15. '0' stands stands for ISO  
8859-15. And relying on LC_CTYPE or LANG, as usual, I get utf-8  
encoded buffers, just as I wish and prefer.


When I first used this statement I thought that GNU Emacs would set a  
few things 'right,' and prefer German man pages, too, or messages/ 
tool tips/comand output/holidays/calendar would come in German. It  
took a long time for me to understand that this particular statement  
was resetting what I had prepared with shell environment variables.

Could be set-language-environment is an obsolete function now that  
GNU Emacs understands LC_ALL or LANG ...

It is not obsolete, but using it is unnecessary if things are set up properly
by default.

Although (set-language-environment "jApAnEse") does set
current-language-environment to the wrong value (so the above two
are not "equivalent").  Following patch will fix it.

You are right, but with your patch, the error message
is always as this:
	Language environment not defined: nil
So, I've just installed the attached change instead.
