Need of Emoji Compatibility

While chatting, reading a mail, researching something on a blog, or reading some stuff on social media you might have encountered [] in the middle of the conversation or content. If you haven’t then you’re most probably using the most compatible tech else you’ll know how these things irritate us or sometimes cause a very bad impression.

See the example below. The person sending the emojis didn’t have a bad intention of saying anything, however, with the emoticons incompatibility that turned out to be pretty weird. This is where you’ll regret not having emoji compatibility in browsers or apps that you’re using.

Devices and emoji format support

Each and every device and browser have their own way of rendering an emoji, which in turn depends on the software they support. This difference in rendering can change the meaning of the text.

Check out this table below which gives a list of devices with different emoji compatibility under the same name.

Browsers that support emoji

Not all browsers support emojis here are the list of browsers that support emojis on different OS

Defining an emoji

To define each emoji there a unicode standard which is always in English. Depending on these Unicodes the device renders them with the help of an application Emoji Support library and displays the correct emoji for the same.

Apart from the unicode there are different names for same emoji on different browsers.
For example, Zeny Face (? Grinning Face With One Large and One Small Eye) is also known as:

  • ? Crazy Eyes

  • ? Excited

  • ? Wild

How to avoid browser emoji incompatibility ?

Google has come up with the solution to this incompatibility. EmojiCompat library is the name. EmojiCompat library by Google keeps a track of emoji updates on every older OS versions. Since the newer emojis are not backward compatible, it appears as [] in older versions. EmojiCompat library prevents your app from showing [] in place of the specific emoji character thus giving you a seamless experience with browsers and apps. But the problem with EmojiComoat is that it’s not the core function of Android, so every developer has to integrate it to the app individually.

How to configure EmojiCompat library?

There are two different fonts configuration for emoji compatibility.

  • Downloadable fonts configuration

  • Bundled fonts configuration

Downloadable fonts configuration

If this configuration do not exist in the device, you need to download these emoji fonts on the run time.

  • Add the following support library in the build.guide file of application.
compile "com.android.support:support-emoji:$version"
Enter fullscreen mode Exit fullscreen mode
  • Now initialize the EmojiCompat using the following codes
class MyApplication: Application() {

    override fun onCreate() {
           super.onCreate()
           val fontRequest = FontRequest(
                   "com.google.android.gms.fonts",
                   "com.google.android.gms",
                   "Noto Color Emoji Compat", R.array.com_google_android_gms_fonts_certs)
           val config = FontRequestEmojiCompatConfig(this, fontRequest)
           // other config settings......
           EmojiCompat.init(config)
       }
    }
Enter fullscreen mode Exit fullscreen mode

Bundled fonts configuration

Your device or your app already has the EmojiCompat package. To use this configuration:

  • Add the following support library in the build.guide file of application.
compile "com.android.support:support-emoji-bundled:$version"
Enter fullscreen mode Exit fullscreen mode
  • Now initialize the EmojiCompat using the following codes
class MyApplication : Application() {
       override fun onCreate() {
           super.onCreate()
           val config = BundledEmojiCompatConfig(this)
           EmojiCompat.init(config)
       }class MyApplication : Application() {

    override fun onCreate() {
            super.onCreate()

    val config = BundledEmojiCompatConfig(this)
            EmojiCompat.init(config)
        }
    }
Enter fullscreen mode Exit fullscreen mode

Now the application is ready to use the EmojiCompat library.

Having fixed the issue of emoji compatibility in list of browsers and devices you need to be sure if they are really made compatible? For this you need to test on various browsers, devices, OSes, and browser versions. You can test the same using LambdaTest and check if your browser renders the emojis you have used.
