Summary0001632: Twemoji not supported
DescriptionHi guys,

I have success with Segoe UI Emoji but looking for a crossplatform opensource alternative.
It seems Twemoji is the most popular and used widely (e.g. Discord)

Here is the COLR version
However, it's rendered as blank glyphs by NoesisGUI. According to the readme:
"Systems that do not support such color fonts will show blank glyphs if they try to use this font."

Here is SVGinOT version
SVGinOT version results in black-and-white glyps only.

I wish to see it implemented—either COLR or SVGinOT.

TagsNo tags attached.

Hmm, that's strange because we already support COLR/PAL tables. That font must have something different. I will have a look at it as soon as possible.

Thanks, Jesús!
I hope it could be done easily, at least for COLR version.
We want to provide certain improvements but don't have much extra time so the idea with emojis support seemed like a perfect one.

NoesisGUI works great with Segoe UI Emoji but due to Microsoft license, we cannot add it into the game Core.cpk. If we use only installed Windows font, Windows 7/8.1 customers will be unable to see the emojis...

If you know any alternative open-source emoji font please let me know. So far I've found only Twemoji and Noto Color Emoji (which is totally incompatible as it never received proper TTF support).

No sure if I am trying the right font. I just downloaded v.0.5.0 from here ( and using the attached XAML I am not able to display anything. Once we release first beta of 3.0 I will be able to analyze this with more detail but could you confirm that with the given XAML you can see black glyphs?

By the way, skin tones and things like that are still not supported. It's been requested many times so I think this is something we will start to solve 'soon' :)

Thanks for checking this.

Mozilla COLR's version of the font is indeed not rendered. I've tried it before and tried again (you can see the attached screenshot #1).

SVGinOT of the font is rendered in black glyphs.

Segoe UI Emoji works fine (see the attached screenshot #2).

I wish we can get support for Twemoji in 2.2.x as so far it's the only viable alternative to Segoe UI Emoji.
We're happy to have just basic emojis support without skin color or other options. It's way better than nothing ha-ha! Actually, it's really incredible, our players who have seen the screenshot of my experiment are totally hyped up! :-)

I would say that COLR version is broken. Not sure if related to this (

Does the font work for you out of Noesis?

SVGinOT is an incredibly complex format, we don't have plans to support it right now... This is something we need to think about again after 3.0...

I've just installed it (as usual — clicked on the font -> Install) and tried in different applications. Most of my apps don't support any Emoji fonts but I had success with MailBird application and Mozilla's COLR version of Twemoji. The second screenshot is Segoe UI Emoji font.

I've simply copypasted emojis from

Could you attach the TTF here? just to make sure we are using the same version.

Ok, finally I found time for this. The problem is, this font is not providing black and white fallback glyphs and we are expecting that. This is a bug in Noesis, I am fixing it right now in 3.0, but I am not sure when I will find time for this for 2.2. Could you create a new version of the TTF with black and white fallbacks?

I am attaching the XAML I am using and a screenshot. The font is cool!

Good to know!
If 3.0 release is coming in mid/late April it would be fine for us :-) no need to implement this in 2.2 then. Otherwise, we would be more than happy to have the fix for 2.2.7...

I'm afraid it's too complicated to rebuild the TTF by injecting the fallback glyphs. I have no experience with this and not enough time to research the idea.

This font is great! Discord is using it so many players would be excited to see this font in their beloved games too!

Yes, the plan is having the final 3.0 earlier. I fixed this (took me more changes than expected to do it efficiently) and will be available in beta 4. Thansk!
