Emoji ☺ symbols
Emoji symbols are the coolest symbols there are, yet they are so fresh, they aren't yet entirely compatible on all of the devices and look a bit different on some of the different ones. Emojis are natively available across all Apple's devices, as Apple is the company that started the trend by creating it's colorful "Apple Color Emoji" font. Also, most emojis are available on Android, and on Windows Phone since version 7, as well as Windows 8 and newer, though, mostly in black and white. On Windows 8, they are also available in color, at least in Internet Explorer. Some sites, Facebook and Twitter for example, simply change emoji symbols into their own colorful font by simply putting images instead of symbols, so that even those who don't have any emoji-containing font installed can see beautiful colorful emojis on their websites.
If you're on a desktop, on this site emoji are available in a custom font that is loaded from the site (273 kb). If you're not seeing them (I have trouble with them on Safari and Internet Explorer on Windows 7, for example), download Android Emoji font. If you're on Safari on Windows, actually, better try on Chrome, or Firefox, on Safari only a small part works for me.
On iOS you can even add an emoji keyboard and type them easily withought having to use FSymbols to access them. I'll miss you, of course.. 😢 Android users, though, make sure you bookmark this page if you like emojis. Anyway, Apple users, you still don't have any native keyboard to input the classical set of cool symbols, so you too should bookmark this page. Click "Emoji" below to deselect emoji set and discover that there are far more great useful symbols other than the colorful emojis. And what is awesome about those is that they are extremely compatible.
