> Good evening, I've been trying to view emojis on Emacs for Android and
> noticed that colored emojis do not appear, while monochrome emojis do
> appear instead. I've only experimented with Noto Emoji Colore and Noto
> Emojis so far.
>
>
> Steps to reproduce:
>
> 1. Install both Noto Emoji (monochrome emojis) and Noto Emoji Color
> (colored emojis) and copy the two .TTF files to ~/fonts
>
> 2. Restart Emacs with -Q
>
> 3. Execute the following
>
> (set-fontset-font t 'emoji '("Noto Color Emoji" . "iso10646-1") nil
> 'prepend)
>
> 4. Try to insert emojis and notice that blank "spaces" are inserted,
> instead
>
> 5. Repeat step 3 but with "Noto Emoji" font and see how the blank spaces
> are filled with the respective monochrome emojis
>
>
> I'm using the latest SourceForge release of Emacs for Android.
>
> If this is not a big but a known limitation known I believe
> it's appropriate to specify it under Android section of the Emacs manual
