Many people like emoji in their smart phones. Now, openSUSE brings emoji into your desktop!

Install colored emoji fonts

openSUSE provides the following colored emoji fonts:

  • Noto Color Emoji (noto-coloremoji-fonts), the default emoji font of most Android smart phones.
  • Emoji One (emojione-color-font), an open source emoji project with best Unicode coverage.
  • Twitter Emoji (twemoji-color-font), used by Twitter website and mobile applications.

You can install one of them. Here is no need to install multiple emoji fonts and it may cause problems.

Test your emoji fonts

Noto Color Emoji in Chromium

Visit Emoji Test which lists all emojis. Firefox is using its built-in Twemoji Mozilla font, no matter what fonts you installed. So it is better to test it in other browsers, like Falkon, Chromium, Vivaldi. You can also test it in Konversation and Kate by copying some emoji.

Why some emojis are black and white?

This is a long story.

Let's take smile face (☺) as example. Its Unicode is \u263A, which has already existed before color emoji was invented. So many text fonts contain it, like DejaVu Sans, Liberation Sans. These Sans Serif fonts have higher priority than emoji fonts. So you will see monochrome fonts used for smile face.

We realized this problem, then. The solution is that emoji variation sequences. \uFE0F means emoji font should be used. \uFE0E means text font should be used. \u263A stands for smile face but it doesn't clarify the choice of text or emoji fonts. \u263A\uFE0F (☺️) will always be shown as colored emoji. \u263A\uFE0E (☺︎) will always be shown as monochrome text symbol.

If you see monochrome (black and white) emoji, the content should be updated. And the tool used to input them should also be updated. Emojipedia and Get Emoji are good example with emoji variation sequences enabled perfectly.

Also, in some cases, the emoji font should be updated to fully support emoji variation sequences. Currently, Noto Color Emoji seems not supporting emoji variation sequences.

Firefox emoji font configuration

Firefox comes with built-in emoji font: Twemoji Mozilla. And it is used by default. To change it to your system emoji font, go to about:config page, search "" and change it to the emoji font name your would like to use.
