如果你的页面设计中需要一些图标，你不必使用图片，也不必使用像 Font Awesome 这样的字体图标，我们要告诉你的是，在你的浏览器中已经有一个庞大的图标和符号库-Unicode。它是一个为每一个数字、字符、符号和图标分配的唯一标识（目前超过11000个）。
这并不意味着你拥有无数的图标，它是通过按钮在系统中的字体，通过浏览器来渲染它们，才出现图标效果。在这个教程中，我们将分享一些在Windows,
Linux, OS X, Android 和 iOS中可用的unicode字符图标。从今天开始，你可以在你的设计中使用它们。这里有一篇关于使用unicode和字符编码的好文章，我们建议每一位开发者都阅读一下这篇文章。
