Using iso-8859-15 with Emacs21 & Gnus

Using iso-8859-15 with Emacs21 & Gnus

[Raymond Scholz]

Hi there!

I'm trying to migrate to iso-8859-15 until January 2002 (time of the €
becoming legal tender in some European countries).

That's what I've done so far:

* XFree 4.1.0 with iso-8859-15 fonts.
* Emacs 21.1
* Oort Gnus
* (set-language-environment "Latin-9")

My own messages are properly encoded in iso-8859-15.  But quoting
parts of other messages that are encoded iso-8859-1 causes Gnus to
create a multipart/mixed message with the quoted parts encoded in
iso-8859-1 and added parts in iso-8859-15.

I know that it's difficult or even impossible for Gnus to determine
whether iso-8859-1 would suffice to encode the whole message.  What I
would prefer is telling Gnus to encode the whole message in
iso-8859-15.  How?

Cheers, Ray

Dave Love has posted a Lisp package for Latin unification to
gnu.emacs.sources.  This might solve this kind of problem.

I forgot to mention that I didn't use Mule-UCS before.  With Mule-UCS
0.84 utf-8 messages are being created.

Tried that but it makes no difference.  With or without Mule-UCS.  But
I may be ignorant of the usage of Dave's package.

Can vanilla Gnus 5.9.0 deal correctly with ISO-8859-15 messages?  Or
do you get multiple parts when you reply to such a message?

Anyway, the current behavior of CVS Gnus + Emacs 21 is not acceptable.
How shall we fix it?  Unify latin-iso8859-1 and latin-iso8859-15
character sets?  Extend the iso-latin-1 and iso-latin-9 coding systems
so that they can encode part of the other charset?  Extend the UTF-8
charset, to make it encode latin-iso8859-15 as well?

The GNU Emacs folks don't seem to be willing to do much work in this
direction because general Unicode support should arrive RSN.

I've put some code into the Gnus CVS to handle this issue.  Please
try. BTW, which charsets are compatible with latin-iso8859-15?

It doesn't work, I'm afraid.  For example, ISO-8859-1 '¼' is changed

to ISO-8859-15 'Œ', which is clearly wrong.

Strictly speaking, none of the other ISO 8859 ones.  But most
characters (not all) can be encoded using ISO-8859-1, too.

Yes, thanks a lot.  However, I think you should unifiy to ISO-8859-1
instead of ISO-8859-15 because the standard utf-8.el can deal with
ISO-8859-1, but not ISO-8859-15.

BTW, there is a typo in the docstrings for 'mm-hack-charsets', and the
docstring for 'mm-iso-8859-15-compatible' seems to be a bit unclear.

I think that in most cases ISO-8859-15 is used because of the euro
sign, which is not convertible to ISO-8859-1.

That's the problem of utf-8.el.

It completely breaks UTF-8 support for Gnus using Emacs 21.  If you
reply to a UTF-8 message, chances are good that it contains ISO-8859-1
characters, and if I understand your code correctly, these characters
are mapped to ISO-8859-15, so the reply cannot be encoded using UTF-8
by Emacs.

But I agree that utf-8.el should support more charsets.

The point is that if a message contains ISO-8859-15, Gnus converts
ISO-8859-1 to ISO-8859-15.

The cases are that if a message contains

1. no ISO-8859-15 chars, no conversion. Fine for utf-8.el.

2. some inconvertible ISO-8859-15 chars (e.g. euro sign), convert
   ISO-8859-1 to ISO-8859-15. No harm, utf-8.el can't encode it either
   way.  

3. no inconvertible ISO-8859-15 chars, convert ISO-8859-1 to
   ISO-8859-15. It would be better to convert them to ISO-8859-1. But
   this case doesn't happen much. Why users input ISO-8859-15 chars if
   they can do it with ISO-8859-1 chars?

To autodetect the case 3 will lose the efficiency.

Presumably, users will switch from a _default_ encoding of Latin-1
now to a default encoding of Latin-9 later.  Most people probably
don't want to use Latin-1 for most things, and Latin-9 only for the
Euro sign -- they want to use Latin-9 in all cases.

At least that's what I would want, as a (more or less) typical German.

Though does USEFOR not specify a default of utf-8?

No.  USEFOR does not specify any default charset.  It doesn't even
encourage reading agents to implement hierarchy-specific default
charsets, which is required in practice.

Anyway, I think Kai was talking about the default charset for posting,
which is properly MIME-declared by Gnus.

Yes it does.  UTF-8 for headers and US-ASCII for the body.

Why on earth would you require UTF-8 handling for the headers and not take
advantage of it for the body?  Oh, wait, right, because we're rewriting
the mail standards without really thinking.

It's this kind of thing that really makes me think it's best to ignore
USEFOR completely for right now.  The lunatics are running the asylum over
there.

Because leaving out the Content-Type header for messages with UTF-8
content in the body cause problems for pre-standard clients and has no
real advantages.

The situation is very different for headers, where both the option of
qp-encoding UTF-8 content in the headers and the option of not
qp-encoding UTF-8 content in the header will cause real problems for
pre-standard newsreaders.  And the option of qp-encoding the header
will cause problems on pre-standard servers.

The cases are not parallel, since MIME does not allow you to specify
character set in headers without QP or BASE64 encoding the content.
In the body, the two functions are ortogonal.

I agree that USEFOR in general are doing too much design and too
little standardization, but I think they took the least bad option in
this case.

In particular since many hierarchies have already a declared a charset
to be the default if no MIME headers are present.  Unfortunately,
USEFOR is completely ignoring this issue and fails to mention that
reading agents need hierarchy-specific charset defaults.

They don't.  It is a quality of implementation issue.

For the headers, I agree, but for the body, no.  There's no such
default in the current draft.

How do you know? ;-)

The draft encourages implementations to recognize UTF-8 even though it
is not declared (and fails to mention the already existing practice of
hierarchy-specific default charsets).

How do I know which?  That news messages are supposed to be MIME messages?
The draft says that pretty clearly, I thought, although it then mentions a
bunch of exceptions like UTF-8 headers.

The draft completely ignores all sorts of existing practice that the

Well, err.  Hm.  I wasn't thinking of this explicitly, but in effect,
that's what I was saying: right now, Gnus uses Latin-1 for German
Umlauts, and after I switch to Latin-9, Gnus should use Latin-9 for
the Umlauts, too.

In the current design of Mule, this would be achieved by the
following chain of events:

* I change (set-language-environment "Latin-1") to
  (set-language-environment "Latin-9").

* Now typing `" a' inserts a Latin-9 ä which Emacs distinguishes from
  a Latin-1 ä.

* Gnus sees non-Ascii Latin-9 characters in my post and chooses
  iso-8859-15 as charset.

After changing Mule to unify the various Latin-* charsets, Emacs does
not distinguish the two variants of ä anymore.  Not sure what that
means to the whole procedure.  Maybe Latin-9 is preferred and used
whenever possible, after set-language-environment?  Maybe.

If unification is present, the whole MIME charset decision process in
Gnus has to be redesigned (and many things can then work in a very
straightforward way).

I meant that I now use (set-language-environment "Latin-1"), and once
I see a real need for the Euro sign I might switch to
(set-language-environment "Latin-9"), instead.

This change affects all of Emacs, so USEFOR is only marginally
relevant, here.

Happens automatically when you call Emacs from an ISO-8859-15 locale:

    LANG=de_DE.ISO-8859-15  emacs

I might misunderstand you, but ISO-8859-1.is used a lot more than
ISO-8859-15 right now.  It is not clear that this will change in the
future, since use is likely to migrate to UTF8 rather than
ISO-8859-15.

I think ShengHuo meant: in most of the cases where -15 is used, it is
used for the euro sign; not: -15 is used more often than -1.

So unifying -15 and -1 to -1 is likely to cause lossage: the original
-15 part probably used to euro, and the unified message won't be able
to.
