 * 计算字符串所占的内存字节数，默认使用UTF-8的编码方式计算，也可制定为UTF-16
 * UTF-8 是一种可变长度的 Unicode 编码格式，使用一至四个字节为每个字符编码
 *
 * 000000 - 00007F(128个代码)      0zzzzzzz(00-7F)                             一个字节
 * 000080 - 0007FF(1920个代码)     110yyyyy(C0-DF) 10zzzzzz(80-BF)             两个字节
 * 000800 - 00D7FF
 * 00E000 - 00FFFF(61440个代码)    1110xxxx(E0-EF) 10yyyyyy 10zzzzzz           三个字节
 * 010000 - 10FFFF(1048576个代码)  11110www(F0-F7) 10xxxxxx 10yyyyyy 10zzzzzz  四个字节
