Discussion on text encoding and Unicode (medium)

, UTF-16, and UTF-32 are encoding schemes that convert numbers to program data. The Unicode Character Set can be abbreviated to UCS (Unicode Character Set ). Early Unicode standards had the saying of UCS-2 and UCS-4. The UCS-2 is encoded in two bytes, And the UCS-4 is 4 byt

Unicode encoding and implementation

Generally speaking, Unicode encoding systems can be divided into two levels: encoding mode and implementation mode. 1.Encoding Method Unicode is a character encoding scheme developed by international organizations to accommodate all texts and symbols in the world. Unicode maps these characters with numbers 0-0x10ffff. It can contain up to 1114112 characters, or contain 1114112 characters. The bitwise is the number that can be allocated to characters. UTF-8, UTF-16, and UTF-32 are encoding scheme

. That is, when the first bit is 0 o'clock, it still represents the usual characters before. When 1 o'clock is the expression of other supplemental characters.There will be no more than 256 English letters plus some other punctuation characters. One byte indicates that the master is enough. But there are some other words, like tens of thousands of characters. Then there are other character sets. So there's a problem with the different character sets. You might be using a number to represent the

specific Symbol correspondence table, may query unicode.org, or the specialized Chinese character correspondence table. The Unicode character set divides all characters into 17 levels (Plane) on a per-use basis, with 216 = 65,536 character code space at each level. The No. 0 level of BMP (basic Multilingual plane base multilingual plane), basically covers all the characters used in today's world. Other dimensions are either used to denote some ancient words or to be extended. The Unicode chara

At the same time that ISO developed the UCs, another joint manufacturer organization was also working on developing such encoding, known as Unicode. Later, the two jointly developed a unified encoding, but released their respective standard documents, therefore, the UCS encoding an
