富连网标准编码格式： UTF-8 • 美国人最后还是有点不爽，而且 UTF-16 没法兼容 ASCII ，在网 络上传输还需要考虑字节序等等各种问题。所以又推出了完全兼容 ASCII 的 UTF-8 格式。 • UTF-32 是固定为 4 字节的编码（实际 Unicode 只有 3 字节） 。 • UTF-16 是在 2 和 4 字节之间变长的编码。 • UTF-8 则是在 1 、 2 、 、 3 、 4 字节之间变长的编码。 • 其中 1 字节就是 ASCII 部分 0x00~0x7F ，剩余的部分根据他们 在 Unicode 中的顺序，依次变长。作为变长编码的代价， UTF-8 需要在二进制中浪费很多额外的空间来表示，导致中文汉字需要 3 字节才能存储。好处是这能完全兼容以前 const char * 的那套代码 ，包括 ‘ \0’ 结尾字符串都可以继续正常使用，不用全换到 GB18030 格式，所以有时候你会发现 Windows 上编辑好的文件，拿到 Linux （往往是 UTF-8 ）的电脑上打开会变成乱码。就是 因为编码格式不匹配的原因。 • 但如果你 Windows 上写日记，只写 ASCII 字符，那么拿到 Linux 就不会有任何问题。因 为 UTF-8 和 GBK 这两个编码格式是兼容 ASCII 的，他保证 0x00~0x7F 仍然是原来那几 个英文字符，因为他们只利用
