unicode converter

unicode converterIt is a tool that can convert Unicode encoding to gb2312 Chinese or Chinese to Unicode encoding. You can also use "Chinese characters to Unicode" without changing the encoding order. Unicode: A computer character encoding. Also known as "Unicode", "Universal Code" and "Unicode Code".

Basic introduction

Unicode: A computer character encoding. Also known as "Unicode", "Universal Code" and "Unicode Code"

Unicode has only one character set. The three characters of Chinese, Japanese and Korean occupy part of Unicode from 0x3000 to 0x9FFF. Unicode is currently commonly used UCS-2, which uses two bytes to encode one character, such as the Chinese character "经" The encoding is 0x7ECF. Note that character encoding is generally expressed in hexadecimal. In order to distinguish it from decimal, hexadecimal starts with 0x, and 0x7ECF is converted into decimal. It is 32463. UCS-2 uses two bytes to encode characters. Two bytes are 16-bit binary. 2 to the 16th power is equal to 65536, so UCS-2 can encode up to 65536 characters. Characters encoded from 0 to 127 are the same as ASCII-encoded characters. For example, the Unicode encoding of the letter "a" is 0x0061, which is 97 in decimal, and the ASCII encoding of "a" is 0x61, which is also 97 in decimal. For the encoding of Chinese characters, in fact Unicode doesn't support Chinese characters very well, so there's nothing we can do about it. There are a total of 60,000 to 70,000 Chinese characters in Simplified and Traditional Chinese, and UCS-2 can represent a maximum of 65,536, which is just over 60,000. Therefore, Unicode can only exclude some rarely used Chinese characters. Fortunately, the commonly used simplified Chinese characters are only more than 7,000. , in order to represent all Chinese characters, Unicode also has the UCS-4 specification, which uses 4 bytes to encode characters.
