Russian numero sign

Russian numero sign

[Paul Pogonyshev]

Activate `russian-computer' input method and type S-3 (i.e. the hash
sign on US English layout.)  This inputs Russian numero sign, which
looks like capital latin `N' with a small underlined circle by the
right side.  (AFAIK, it was also used in French typography before.)

Now, Emacs puts this character in the buffer (output of
`describe-char'):


  character: � (3696, #o7160, #xe70)
    charset: cyrillic-iso8859-5 (Right-Hand Part of Latin/Cyrillic Alphabet (ISO/IEC 8859-5): ISO-IR-144.)
 code point: #x70
     syntax: . 	which means: punctuation
   category: y:Cyrillic
   to input: type "#" with russian-computer
buffer code: #x8C #xF0
  file code: not encodable by coding system mule-utf-8-unix
    display: by this font (glyph code)
     -ETL-fixed-medium-r-normal--16-160-72-72-C-80-ISO8859-5 (#xF0)


Which means that you cannot save this character into an UTF-8 file
even though UTF-8 is meant to be able to encode anything in Unicode.

There is actually a Unicode character `numero sign', U+2116, which I
can type in other desktop applications (probably through XIM) by
the same Shift-3 combo with Russian layout.  When copied into Emacs,
this character is displayed as a box (i.e. no glyph for it is found)
and is described like this:


  character: № (342742, #o1235326, #x53ad6, U+2116)
    charset: mule-unicode-0100-24ff (Unicode characters of the range U+0100..U+24FF.)
 code point: #x75 #x56
     syntax: w 	which means: word
buffer code: #x9C #xF4 #xF5 #xD6
  file code: #xE2 #x84 #x96 (encoded by coding system mule-utf-8-unix)
    display: by this font (glyph code)
     -Adobe-Courier-Medium-R-Normal--17-120-100-100-M-100-ISO10646-1 (#x2116)


So, is there an easy way to fix Emacs to input the Unicode character
instead of that 3696 or make them same character somehow?  It is kind
of annoying that I cannot input the numero sign in an UTF-8 buffer
even though I have a key for it on the keyboard.  I don't really care
if the glyph is not found, it is probably a deficiency in the font,
not Emacs, but I think UTF-8 unencodable characters is something that
should not exist at all, especially when you have the corresponding
Unicode character.

Try unify-8859-on-decoding-mode, which changes the behaviour of your
input method.

Alternatively use unify-8859-on-encoding-mode, than cyrillic-iso8859-5
is preserved during input, but still can be saved as UTF-8.  Of course
you get UTF-8 when you load the file again, so you will need font
support for that anyway.

With `unify-8859-on-decoding-mode' I get squares instead of letters (no
glyphs in the font, apparently), the second one seems to work perfectly.
Any reason it is not the default?

But, unify-8859-on-encoding-mode should be on by default (at
least with CVS HEAD emacs).

Paul, do you turn it off intentionally?  Can you reproduce
this problem by starting your emacs with "-Q"?

Uh, indeed.  I think I turned it off because of poor support of
Cyrillic characters by the fonts...  If I start it with `-Q',
the numero sign is automatically encodable in UTF-8 as it
should be, but the Cyrillic characters appear as boxes which is
of course even worse for me.

I wonder if Emacs could implement some smart font substitution
when a glyph is not available in a font.  You can see what I
mean in e.g. recent `gnome-character-map' (it actually seems to
be a very nice trait of all GTK+/Pango programs.)  My `standard'
desktop font is Bitstream Vera Sans and all common characters
are displayed in this font in GNOME Character Map.  However,
certain characters are displayed in other fonts, presumably
because glyphs for them are missed from Bitstream Vera Sans.

Now, if I create a string of symbols in the Character Map and
copy it into another program, I get these results:

* GTK+ (hence Pango) programs: symbols that are displayed OK
  in the Map are displayed OK here too.

* KDE/Qt programs: symbols that are displayed with the Bitstream
  font in the Character Map are displayed OK (my KDE is
  configured with Bitstream Vera Sans as default too), other
  symbols (drawn with different fonts in the Map) are shown as
  boxes.  Apparently, Qt lacks font substitution just as Emacs.

* Emacs is the worst, since it uses `adobe-courier'.

So I think Pango fallback mechanism is great since many fonts
are really poor wrt number of provided glyphs.  It would be
really nice if Emacs could use something symilar or even relay
font/glyph-related tasks to Pango.  Not in the upcoming release,
of course, but I think it is one of the areas where improvement
is certainly needed.

unify-8859-on-encoding-mode is not relevant how to read (or
decode) Cyrillic characters encoded in UTF-8, nor how to
display Cyrillic characters decoded into
mule-unicode-0100-24ff charset.

Do you really mean that you solved the display problem by
turning it off?

Anyway, your display problem is because of your
adobe-courier-*-iso10646-1 font doesn't support Cyrillic
characters.

Please try to select "fontset->standard" by shift-mouse1.
It makes "fixed" the default family, thus has the higher
possibility of selecting an iso10646-1 font that support
Cyrillic.

If that doesn't help, or you don't want "fixed" the default
family, please find a family name of an iso10646-1 font that
support Cyrillic, and try this:

(set-fontset-font
 "fontset-default"
 'mule-unicode-0100-24ff
 '("_HERE_COMES_FAMILY_NAME_" . "iso10646-1"))

I implemented such a feature fairly long ago in
emacs-unicode-2 branch.  Unfortunately, Emacs of CVS HEAD
lacks infrastructure to support it.

Does it show the text, when you kill the buffer and re-load the saved
UTF-8 file?

It seems to be the default on my system but that may be because I use
a CVS version or because of my environment.

No, there is a misundestanding.  I meant `unify-8859-on-decoding'.
In general, Emacs shows most basic characters OK with unify-on-encoding
turned on and unify-on-decoding off, it's not like I need fancy
characters regularly.  However, Pango sure does a nicer job and I hope
your changes doing similar things get merged into the Emacs trunk.  That
is, if another stable version is ever released.

This doesn't seem to have any effect.  The screen flickers but displays
exactly the same fonts, no matter what I choose in the menus.  Probably
because I have customized faces, not sure.

So, you turned off unify-8859-on-decoding to solve the
display problem, right?

Then I think the reason why you can't see Cyrillic
characters while unify-8859-on-decoding is on is that your
-adobe-courier-*-iso10646-1 font doesn't contain Cyrillic
glyphs.

Please note that Pango and the other modern rendering
engines use TrueType font with a help of freetype/Xft and
fontconfig libraries.  Emacs (and emacs-unicode-2 too)
currently doesn't use them, but there exists an ongoing
project for supporting TTF in Emacs.

First of all, do you have any iso10646-1 X core fonts that
support Cyrillic characters?

Yes.  When it is off, newly typed Cyrillic characters are displayed OK.
When it is on, newly typed characters are displayed as boxes, even if
the buffer visiting an UTF-8 file already contains properly displayed
Cyrillic characters.

Yeah, I suspected that all the way :)  However, Emacs can do nothing
about the fact that the fonts out there don't provide support for all
the Unicode characters (and most fonts actually provide support for
only a tiny fraction of characters...)  Emacs could, however, use
multiple fonts to alleviate the problem, that's what I'm proposing
(for a future version.)

That is a valid reason why Emacs cannot use Pango (yet), but it
doesn't mean Emacs cannot implement similar substitution heuristic
without Pango and for a different font class.  As I understand, you
did that in the `emacs-unicode-2' branch.  It is not something simple,
but Emacs is not simple to begin with.

No idea, sorry.  How do I check?  As I wrote above, Emacs does
display Cyrillic characters (newly typed) when `unify-8859-on-decoding'
is off.  And already existing characters are displayed no matter if
that mode is active or not.

I drastically changed the internal structure of fontset in
emacs-unicode-2.  We can't do such a change for the HEAD
(which will be the next release, I hope, soon).

% xlsfonts -fn -*-*-medium-r-normal-*-*-*-*-*-*-*-iso10646-1

gives you a list of iso10646-1 X core fonts usable from
Emacs.  For instance, if this font is found...
-misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1

% xfd -fn -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1

shows you the supported glyphs.  Please check the block
0x000400.  If you see cyrillic glyphs there, that font is
what you need.  You can do this to use that font.

(set-fontset-font
 "fontset-default"
 'mule-unicode-0100-24ff
 '("FOUNDRY-FAMILY" . "iso10646-1"))

Here FOUNDRY-FAMILY is misc-fixed in the above case.

If you surely don't have a proper iso10646-1 font, the next
method you can try is to customize utf-fragment-on-decoding
to t.  Even with the default setting of
unify-8859-on-decoding/off and unify-8859-on-encoding/on, if
utf-fragment-on-decoding is on, when you read an utf-8
cyrillic file, characters and decoded into
cyrillic-iso8859-5 charsets, thus you should see glyphs with
your iso8859-5 fonts.

Yes, I have Cyrillic characters in misc-fixed and don't have them in
adobe-courier.

I went to install all the fonts I could find in my Debian Sarge.  And
found cronyx-courier font, which looks nice _and_ has Cyrillic
characters.  However, when I customize the default face in Emacs and
set that font family, latin characters are still displayed in
adobe-courier (though Cyrillic ones are shown in cronyx-courier)...
And the customization doesn't take any effect after I restart Emacs...
Any ideas?

Perhaps that because you don't have
-cronyx-courier-...-iso8859-1.  Emacs by default uses an
iso8859-1 font for ASCII.  To change it, you must create a
proper fontset by one of these ways:

(1) In your .emacs:

(create-fontset-from-fontset-spec
 "-cronyx-courier-medium-r-normal--17-*-*-*-m-*-fontset-cronyx17,
ascii:-cronyx-courier-medium-r-normal--17-*-*-*-m-*-iso10646-1")

Then, after you start Emacs, by selecting fontset-cronyx17
with s-mouse-1->fontset->cronyx17, Emacs change the default
fonts to cronyx-courier.

(2) Setting X resource:

When you set these resources,

Emacs.Fontset-0: -cronyx-courier-medium-r-normal--17-*-*-*-m-*-fontset-cronyx17,\
!ascii:-cronyx-courier-medium-r-normal--17-*-*-*-m-*-iso10646-1

Emacs.Font: fontset-cronyx17

you can start emacs automatically with a proper font.

Another one time way is to start Emacs as this:

% emacs -fn -cronyx-courier-medium-r-normal--17-*-*-*-m-*-iso10646-1

Maybe too late to answer, but I solved it by adding the code above
and

(setq default-frame-alist
      (cons (cons 'font
		  "-cronyx-courier-medium-r-normal--17-*-*-*-m-*-iso10646-1")
	    default-frame-alist))

in my `.emacs'.

Thanks.

Do you mean that the methods I suggested didn't work?

It worked, but I automated it by modifying `default-frame-alist', so
that there is no need to choose fontset by hands.  (In fact, I later
abandoned cronyx courier since it is not completely fixed-width, but
that is a separate matter.)  So, your code is fine except that it
requires minor manual intervention.
