Maybe everyone has heard of Unicode, UCS-2, UTF-8 and other words, but what they specifically mean, what is the principle
, from the location code to the inner code, you need to add A0 on the high and low byte respectively.In DBCS, GB internal code storage format is always big endian, that is, high in front.The highest bit of the two bytes of the GB2312 is 1. But the code bit that meets this condition is only 128*128=16384. So the low-byte highest bits of GBK and GB18030 are probably not 1. However, this does not affect the parsing of DBCS character streams: When reading a DBCS character stream, you can encode the

the initial Unicode encoding is a fixed-length , 16-bit, or 22-byte representation of a character, which can represent a total of 65,536 characters. Obviously, it is not enough to represent all the characters in a variety of languages. The Unicode4.0 specification takes this into account, defines a set of additional character encodings, which are represented by 2 16-bit characters, so that up to 1,048,576 additional characters can be defined , and currently unicode4.0 only defines 45,960 additio
ASCII, gb2312, and GBK to gb18030 are both backward compatible. Among them, gb2312 and GBK to gb18030 both belong to the dual-byte character set (DBCS character set)Unicode is ANSI compatible. For example, the Unicode encoding of the Chinese character is 6c49, And the GB encoding is Baba.The Unicode name is "Universal multiple-octet coded chasracter set", for shortUCOS only specifies how to encode and does not specify how to transmit and save the encoding. For example, the "Han" character's
Recently, a number of Cisco ucs c Series servers have been added. After two weeks of deployment and installation, the server can finally be tested. This document briefly introduces the network configuration of the Operating System (centos 6) in the Cisco UCS server. It can be simply considered that this article describes the network configuration of a physical server connecting the NIC to the trunk mode por

The general character set of UCS (Universal Character Set) is independent of the character set independent character set.
It means that the language converts the text into an internal character set before process
ASCII and related standards
The earth people all know ASCII is the abbreviation of the American Standard Information Interchange code, also know that the ASCII stipulation uses 7 digits binary numeral to represent English character, the ASCII is designated as international standard after the code name is ISO-646. Since the ASCII code uses only 7 bits, that is, a byte can represent 256 digits, it uses only the 0~127 128 code bits, the remaining 128 code bits can be used to expand, to represent s

This section describes the UTF-8 encoding.
When the content to be expressed is 7 bits, use one byte: 0 ********. The first 0 is the flag, the remaining space can represent the content of ASCII 0-127.When the content to be represented is between 8 and 11 bits, two bytes are used: 110*10*10 of the First and

In short, the UNICODE,GBK and the big five yards are encoded values, and the utf-8,uft-16 is the representation of the value. The previous three codes are compatible, the same characters, and the three yards are completely different. such as "Han" Uncode value and GBK is not the same, assuming that uncode for A040,GBK b030, and Uft-8 code, that is the form of the value expression.

2. Unicode, UCS and UTF
Previous coding methods from ASCII, GB2312, GBK to GB18030 are backward-compatible. Unicode is compatible with ASCII only (or, more accurately, iso-8859-1 compatible), and is not compatible with GB code. For example, the Unicode encoding of the word "Han" is 6c49, while the GB code is baba.
