Again, it is necessary to emphasize that both the historical UCS and today's Unicode, both refer to the coded character set, not the character set encoding. Take a little time to understand this, and then you will find that all the pages, the system, the coding standards of the back and forth between the conversion and so on complex affairs will be clear, extremely easy. First, the most common sense of the character set. An abstract character set is

The characters defined in BMP can be encoded by 16 characters, that is, a UTF-16 of only one word (word, 2 bytes.Plane 0 (0000-ffff ):Basic multilingual plane(BMP)Therefore, Windows API, wchar/w_char (w_char can be 4 bytes from the Language Perspective), and char in Java/C # only supports BMP. Although the UTF-16 is variable-length encoding, it is not like the UTF-8, it can be 1, 2, 3, 4 bytes, it can only be 2 or 4 bytes. 8. How many characters can Unicode contain? Is it dubyte?U

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

What is UTF-8? First, only an integer is allocated to the character encoding table. there are several methods to represent a string of characters as a string of bytes. the two most obvious methods are to store Unicode text as strings of 2 or 4 byte sequences. the formal names of the two methods are UCS-2 and UCS-4, respectively. unless otherwise specified, most of the bytes are like this (bigendian Conventi

What is Unicode? A mapping with characters and A is index, we use U+XXXX to represent it. Confuse with Unicode and UTF-8?

Universal Character Set (UCS) UCS is a standard character set developed by ISO 10646(or ISO/IEC 10646) standards.The UCS includes all other character sets (which contain the known language's characters).ISO/IEC 10646 defines a 31-bit character set (the first constant is 0, which takes up 4 bytes).Unicode (Universal code, International Code, Uniform Code, si

About the Unicode character set(2011-10-20 20:54:03)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, an

of multi-word segments. For example, the Unicode code of the Chinese character is 6c49. When I write a file, do I write 6C in front or 49 in front? If you write 6C in front, it is bigendian. Write 49 in front, that is, little endian. The word "endian" comes from Gulliver Travel Notes. The civil war in the minor people's country originated from the fact that the big-Endian attack or the little-Endian attack were initiated when the eggs were eaten. As a result, there were six rebels, one of the e
