What is unicode?

Unicode is a character encoding scheme that sets a unified and unique binary encoding for each character in each language to achieve cross-language and cross-platform text conversion and processing requirements.

##Unicode (Unicode, Universal Code, Unicode) is an industry standard in the field of computer science, including Character sets, encoding schemes, etc. Unicode provides a unique number for each character, no matter what platform, no matter what program, no matter what language. Unicode was created to solve the limitations of traditional character encoding schemes. It sets a unified and unique binary encoding for each character in each language to achieve cross-language and cross-platform text conversion and processing requirements.

Unicode is a character encoding scheme developed by an international organization that can accommodate all texts and symbols in the world. The current Unicode characters are divided into 17 groups, 0x0000 to 0x10FFFF, each group is called a plane, and each plane has 65536 code points, a total of 1114112. However, only a few planes are currently used. UTF-8, UTF-16, and UTF-32 are all encoding schemes for converting numbers into program data.
