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

utf-16 code. We found through the search that the 4-byte utf-16 encoding range is u+010000 to u+10ffff, so our regular can be written like this:/[\u010000-\u10ffff]/g? No, you will find that this regular does not work as we expect. What is this for?The above question, some children's shoes may already know the answer. Yes, it's the JavaScript coding problem that's causing it. We know that JavaScript uses Unicode encoding, and, to be exact, ucs-2 enco

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

In this language environment, there will be no more language coding conflicts, under the same screen, can display any language content, this is the greatest advantage of Unicode. So how is Unicode encoded? actually very simple. is to encode all the text in the world in 2 bytes. You might ask, 2 bytes can represent up to 65,536 encodings, is it enough? Most of the Chines

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

It should be emphasized again that, whether in the history of the UCS or the current Unicode, both referEncoding Character SetInsteadCharacter Set Encoding. It takes a little time to understand this matter, and then you will find that the logic of switching back and forth between all webpages, systems, and coding standards is clear and easy to understand. First, let's talk about the character set in the most general sense.One Abstract Character Set I
