Re: getting utf-8 from textual_run in redisplay-xlike-inc.c for Gtk display.

Ar an triú lá de mí Aibréan, scríobh Jeff Sparkes: > I've got pango displaying the strings from the output_string function in > redisplay-xlike-inc.c. 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.
