Missing Emoticons or Emojis on Arch Linux

Emoticons are not appearing on Instagram, but you can resolve this issue by installing Twemoji from the AUR.

Here’s the list of Twemoji packages to install:

• Truetype builds of Twemoji; Twitter Color Emoji for everyone: ttf-twemoji
• A color and B&W emoji SVG-in-OpenType font by Twitter with support for ZWJ, skin tone modifiers, and country flags: ttf-twemoji-color
