摘要： 今天中午，我突然想搞清楚Unicode和UTF-8之间的关系，于是就开始在网上查资料。结果，这个问题比我想象的复杂，从午饭后一直看到晚上9点，才算初步搞清楚。下面就是我的笔记，主要用来整理自己的思路。但是，我尽量试图写得通俗易懂，希望能对其他朋友有用。毕竟，字符编码是计算机技术的基石，想要熟练使用计算机，就必须懂得一点字符编码的知识。1. ASCII码我们知道，在计算机内部，所有的信息最终都表示为一个二进制的字符串。每一个二进制位（bit）有0和1两种状态，因此八个二进制位就可以组合出 256种状态，这被称为一个字节（byte）。也就是说，一个字节一共可以用来表示256种不同的状态，每一个状态 阅读全文
