[Bug 1615575] Re: Emoji support

[marmuta]

Thanks for the quick response, Brad.

I agree, launchpad works quite well for us. There's not really much
pressure to move away, currently. Also, I feel, as long as Onboard is
installed by default in Ubuntu, we should stay close. The situation may
change with unity 8, we'll see.

Seems you were right, there's support for (what I believe is) Google's CBLC/CBDT in freetype. I got this example here
https://gist.github.com/jokertarot/7583938
to render colored emoji from your emojione-android.ttf.
That could be a possible path forward. Don't know if this is accessible from anywhere higher in the stack.

For SVGinOT there's just this bug report:
https://savannah.nongnu.org/bugs/?46141

I'd still prefer SVG over png for Onboard, though, because most of the
UI is freely scalable. All the other images we use as key labels are SVG
too.

That's what we currently do, yes. If there's no reasonable way to get color, we'll just wait for better times.

I've seen that the fonts-emojione Ubuntu package has gray-scale glyphs. Is that a special version of your font or a fallback? They render fine in Onboard, btw.
