example of broken ligature coloring

When I try to apply a different color to a text selection that is connected to another letter via a ligature from left border, the character before selection gets recolored too.

See attached image for a sample, where instead of two selected characters three get recolored.

It does not happen with all ligatures though, as far as I can see.

The font in question is here:

http://www.google.com/webfonts/family?family=Lobster&subset=cyrillic#download

I have a suspicion that newly filed https://bugzilla.gnome.org/show_bug.cgi?id=648155 has something to do with it, but it's not my job to decide :)

This is the markup:

<markup><span font=\"Lobster 1.4,\">simple e<span foreground="#00aeff">xa</span>mple</span></markup>

So clearly no a GIMP problem.
Comment 2 Michael Natterer 2011-04-18 22:38:26 UTC
And not my job to decide either :) -> pango
Comment 3 Michael Natterer 2011-04-18 22:40:35 UTC
Completely unescaped markup:

<markup><span font="Lobster 1.4,">simple e<span foreground="#00aeff">xa</span>mple</span></markup>

I think I kinda found a solution for this. For multi-color ligatures we can use a cairo gradient with sharp transition to do multi-color without having to fall back to clipping.
Comment 5 Alexandre Prokoudine 2016-06-03 01:19:06 UTC
It was clearly a mistake on my part to report this as a bug. Ligatures are ligatures.
Comment 6 Behdad Esfahbod 2016-06-03 21:50:03 UTC
Actually no, this *is* a bug.
