I've got pango displaying the strings from the output_string function in
redisplay-xlike-inc.c.
Pango wants utf-8 input. I have HAVE_XFT and MULE defined, so I'm getting
separate_textual_runs_xft_mule(), which is converting it into XftChar16,
which is probably UCS-2, not UTF-16?
There isn't even a Qucs_2 anywhere. There is a unicode_convert in
unicode.c, but I don't know how
to use it, and it involves Dynarrs.
I'm not even 100% sure what I'm asking for!

Excellent! And I’ve been occasionally building the GTK workspace over the
last few weeks, and getting a running XEmacs; thanks for that, it does make
a difference.

It should be UTF-16, that’s what XftDrawString16 accepts. XEmacs only treats
it as UCS-2 at the moment, which is a shame, but with our font support
passing surrogates probably wouldn’t be much help anyway. (I’m not sure you
want to turn on HAVE_XFT at the same time as Pango with GTK2 and XFT;
HAVE_XFT means “use our XFT redisplay implementation on top of X11 and the
Athena widgets”).
But that’s irrelevant to you. The good news is the Xft code used to do
exactly what you want; see the separate_textual_runs_xft function in this
patch:
http://www-pu.informatik.uni-tuebingen.de/users/knauel/xemacs-xft/xft-xem...
There will be better long-term solutions, but this is enough for your
purposes at the moment, I think. Shout if you have any trouble understanding
it.

Wow, an actual customer! My biggest problem for a semi-release is
getting the toolbar to display correctly. The display is working well
for ASCII characters.

It should be UTF-16, that’s what XftDrawString16 accepts. XEmacs only treats

I have HAVE_XFT turned on because pango can use fontconfig fonts.
But that’s irrelevant to you. The good news is the Xft code used to do
exactly what you want; see the separate_textual_runs_xft function in this

Excellent. I haven't had a chance to try it out yet. I have a crash
which seems to be related to charset converage.

I believe it's UTF-16, except that there's a comment saying we don't
handle anything outside the BMP. (There's really no point in talking
about UCS-2 any more, but that's outside the scope of this
discussion.)
You may as well use encode_unicode_char_1, I think, and just learn to
use Dynarrs. Here all you need to do is declare one, hand it to
encode_unicode_char_1, and then extract the data (probably as a
pointer and a length) and hand it to Pango. I guess you may need to
deallocate afterward. But all of the "interesting"w stuff is already
done in encode_unicode_char_1, you don't have to worry about it.
