Utilizing Emoji Fonts on Your Website: A Simple Guide

I have recently installed Google's "Noto Color Emoji" font, but unfortunately, I am encountering some issues with making it work. While other fonts like "Noto Sans Regular" function without any problems, the "Noto Color Emoji" font is causing errors in Firefox on Windows 10:

downloadable font: no supported glyph shapes table(s) present (font-family: "NotoColorEmoji" style:normal weight:normal stretch:normal src index:0)
downloadable font: rejected by sanitizer (font-family: "NotoColorEmoji" style:normal weight:normal stretch:normal src index:0)

Interestingly, I am facing the same troubles with Chrome, Internet Explorer, and Edge on Windows 10, as well as with Firefox on Ubuntu Linux.

Below is the code snippet that I am using: 

<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <style type="text/css">
        @font-face {
            font-family: 'NotoColorEmoji';
            src: url('NotoColorEmoji.ttf') format('truetype');
        }
    </style>
</head>

<body>
    <span style="font-family: 'NotoColorEmoji'">Emojis: 😀😬😁😂😃😄😅😆😇😉😊🙂</span>
</body>

I am puzzled about what could be going wrong. Are Emoji fonts supposed to be implemented differently?

Answer №1

Color fonts are on the horizon, but there are a few ways to approach implementing them:

  • Create a single font with all color formats (4 total!), although this could result in a massive file size and may be overly complex.
  • Develop separate fonts for each format and load them conditionally, although this method is not recommended due to potential large file sizes (+20MB) for bitmap-based formats.
  • Wait for widespread support of the OpenType SVG format.
  • Explore JavaScript solutions like
    • Twemoji, a library that offers standard Unicode emoji support across platforms.
    • EmojiOne, an open source emoji standard.

For now, using the OpenType SVG format appears to be the most promising solution for web applications!

We're excited to share the progress of our latest project, an innovative Emoji library called OpenMoji.

Right now, we have successfully implemented a custom .ttf font that can be easily integrated into your website.

  1. Get your hands on the font by downloading it from this link. 💾
  2. To include the font in your design, use the following code snippet:
@font-face {
  font-family: 'OpenMoji';
  src: URL('OpenMoji-Color.SVG.ttf') format('truetype');
}
  1. Enjoy and celebrate with us! 🥳 If you have any inquiries or feedback, don't hesitate to reach out to us here.

Answer №3

Color fonts are a relatively new concept with multiple competing standards that are still in the process of evolving and being incorporated into common text libraries (Opentype 1.8 has recently been released introducing another element to color fonts).

Currently, they may not function properly except in the most up-to-date preview browsers, and even then, the level of support can vary depending on the operating system being used, as browsers rely on system text libraries (each with its own sets of overrides).

Older software is unlikely to recognize the Opentype extensions required for these fonts to work.

Furthermore, Noto Color Emoji is essentially a prototype at this point, early versions may not fully comply with later standardizations, and even if they do, the methods for utilizing color font standards are likely to continue to evolve as both font producers and consumers become more experienced in this area.

Answer №4

I love using the 'Segoe UI Emoji' font-family for my emojis. This awesome font works seamlessly on Chrome, Firefox, IE11, Mac Safari, and even mobile Safari. I'm thrilled that most emojis display perfectly, even the ones that lack color in regular fonts like the mountain, speech bubble, and paintbrush.

Unfortunately, it's a bummer that this font doesn't work on Android devices :(
