UTF-8 是一种 Unicode 的实现手法, 它依然遵守 1 byte = 8 bits 原则. 刚才我们说 ASCII 用了后面 7 个 bits, 最前面还有一个 bit 是 0. 这就让它有了利用价值. 如果发现开头是 1 就表示它是一个 Unicode 然后需要去拿下一个 byte. 具体规则看这里. 总之就是一种解析规则, 通过识别几个 bytes > ...

A 8-Bit Binary code (Byte) is capable of representing 28 (256) distinct values ranging from 0 to 255. It is frequently used to represent characters (ASCII), colors, and a variety of other data formats. A 16-bit binary code may encode 216 (65,536) distinct values, giving it a wider...

1、ASCIIASCII全称(American Standard Code for Information Interchange)美国信息交换标准代码,在计算机内部中8位二进制位组成1个字节(8(比特)bit=1(字节)byte),而ASCII的编码方式是把一个字节中的低7位用来编码,最高位也就是第8位留着不用(最高位一般为0,但有时也被用作一些通讯系统的奇偶校验位),从0x00一...
