* [PATCH] Add non-ASCII characters to morse.el

Is there a better way to represent non-ASCII in elisp?  If anyone has
a better source of non-ASCII morse characters, it might be useful as
well.  Unfortunately, I think morse has been dropped as an official
language, so a canonical source might be difficult to find.

What do you mean?  Some way other than Lisp string?

This page shows Japanese version of morse.  But, perhaps,
it conflicts with English morse.

It seems that this entry doesn't work because mouse-region
checks characters one by one.

Yes.  The coding system used by *.el doesn't seem fixed, so if I add a
morse sequence for the euro sign by storing the euro sign literally,
someone else opening the file might read it as a Latin-1 currency
symbol -- and emacs treat the two characters as distinct.  Should I
add a charset cookie to the file perhaps?

They do conflict.  Interesting.  Is there a universal morse prefix for
language tagging morse code?  Can we use emacs internal charset
guessing algorithm for deciding which morse language to use?  Perhaps
this is too complicated for a toy package.  Unless someone wants to
work on it, I think we should only add non-conflicting characters.
(One character missing in my patch was .../... for ß.)

Thanks.  I think it is supposed to be only one character (a
ligature?), but I don't know how to produce it.

Yes.  And I recommend the utf-8 cookie if it's an option.

OK.  Is it ok to install the patch below?  I didn't find the Ch
ligature so I left it in a comment.

Probably a Gnus problem: your patch were converted to iso-8859-1 -- I
guess you forgot to protect the diff using these "mml" tags and
Emacs/Gnus happily unified UTF-8 to the default encoding.

Yup.  It is a feature, actually, since more people support ISO-8859-1
than UTF-8, so if UTF-8 can be expressed as ISO-8859-1 (which was the
case here, I believe) Gnus downgrades it.  I was happy to see that it
actually works in practice.  The commited file should be in UTF-8
though.
