unicode superscript 2

Let's first explain why we need to convert Chinese to unicode encoding. Unicode plays an important role in general international standards. It is more byte-saving than traditional character encoding, enabling the design of web pages to be displayed on platforms of different languages, therefore, as long as the Chinese character is converted to Unicode, no garbled

UTF code The UTF-8 is to encode the UCS in 8-bit units. The encoding method from UCS-2 to UTF-8 is as follows: UCS-2 encoding (16-in-system) UTF-8 byte stream (binary) 0000-007f 0xxxxxxx 0080-07ff 110xxxxx 10xxxxxx 0800-ffff 1110xxxx 10xxxxxx 10xxxxxx For example, the Unicode encoding of the word "Han" is 6c49. 6c49 between 0800-FFFF, so be sure to use the 3-byte

UTF encoding The UTF-8 is to encode the UCS as a 8-bit unit. The encoding from UCS-2 to UTF-8 is as follows: UCS-2 encoding (16 binary) UTF-8 byte stream (binary) 0000-007f 0xxxxxxx 0080-07ff 110xxxxx 10xxxxxx 0800-ffff 1110xxxx 10xxxxxx 10xxxxxx For example, the Unicode encoding of the word "Han" is 6c49. 6c49 is between 0800-ffff, so I'm sure to use a 3-byte te
