I've discovered this when trying to fix emoji displaying in notifications for Wazapp.
Final result was that it was enabled system wide.

Thanks to all the testers, big thanks to Michael for making keyboards, packaging and publishing.

Special thanks to Flopjoke and Brkn that have worked relentless on making and baking the font in early stages with me.

Technical answers:

Only Apple has colored emojis because they used a special Unicode6.1 font embedding PNGs and preparing OS for it.

Harmattan system apps can display only black and white.
3rd party apps will have an API to use if they wish to use PNGs in color. Their apps will just work without any change with black and white. I've tested with most of popular apps.

Porting to Freamantle could be possible of someone reports back of the OS uses Fontconfig.

Maliit doesn't support PNG in keys. Askes the dev, he says it's interesting and will consider it.


For every other question please approach Michael.
I just hack stuff when we need them.
