[Unicode] character encoding table information, unicode character encoding
The UTF-8 is somewhat similar to the Haffman encoding, which encodes Unicode:
0x00-0x7F characters, expressed in a single byte;
The character 0x80-0x7FF is expressed in two bytes;
0x800-0xFFFF characters are represented in 3 bytes;
① The unicode range of a number is 0x0030 ~ Zero x 0039
