How much do you know about character set encoding Ascii,unicode and UTF-8? This article will give you a thorough understanding of character set encoding. This article describes the problems and transformations of Ascii,unicode and UTF-8 coding, as well as example analysis. Start reading the article.

We know that inside the computer, all information is ultimately a binary value. Each bits (b
multiple bytes. For example, the common encoding method for simplified Chinese is gb2312, which uses two bytes to represent a Chinese character. Therefore, it can theoretically represent a maximum of 256x256 = 65536 characters.
The issue of Chinese encoding needs to be discussed in a specific article. This note does not cover this issue. It is only pointed out that although multiple bytes are used to represent a symbol, the Chinese character encoding of the GB class has nothing to do with the
industrious and simple Chinese people have developed the GBK (GB2312 extension) encoding, which is an ASCII-compliant indefinite length (length of 1-2) encoding, for the basic 128 characters are still in one byte, but "Xiang" in Chinese is expressed in two bytes:Similar to GBK, UTF-8 is also an indefinite-length encoding that is compatible with ASCII codes, which vary in length and can therefore represent almost all world text.

If you're a programmer who lives in the 2003, you don't know the basics of character, character set, encoding, and Unicode. Then you must be careful, if I catch you, I will let you peel six months of onions in the submarine to punish you.
This vicious threat was first made by Joel Spolsky ten years ago. Unfortunately, many people think he's just joking, so there are still a lot of people who don't fully understand
Char is the underlying type of Java (the original type) and is a character type. Characters in Java are Unicode-encoded, so a Java character occupies 2 bytes, and the content of the character is stored in Unicode code values (binary numbers). The question is, how does the program convert Unicode code values to the program data we want? For example: Chinese charac
The string also has an encoding problem.Because a computer can only handle numbers, if you are working with text, you must convert the text to a number before processing it. The oldest computer was designed with 8 bits (bit) as a byte (byte), so the largest integer that a Word energy saver represents is 255 (binary 11111111 = decimal 255), and 0-255 is used to denote uppercase and lowercase letters, numbers, and some symbols. This Code table is called ASCII encoding, such as the code for capital
develop a long-term vision, then no matter what you set the encoding method, will not make the data generated garbled. Because, here is the universal code--unicode.
Well, the question is, how do we solve it? By experimenting, Jackson JSON actually has the ability to parse Unicode-encoded JSON data with the default settings. What is missing is the lack of steps to serialize the object. Fortunately, the Jac
My readers know that I am a man who likes to scold Python3 Unicode. This time is no exception. I will tell you how painful it is to use Unicode and why I can't shut up. It took me two weeks to study Python3, and I needed to vent my disappointment. In these scolding, there is still useful information, because it teaches us how to deal with Python3. If I'm not bothered by it, read it.

I have never figured out what the Unicode Character Set and uft-8 encoding are like in The ascall character set.

Unicode
(Computer) The most common standard character set after ASCII. ASCII is still the foundation of computer operation. However, there are too few. It cannot keep pace with the development of computer applications. Unic
based on ASCII 127 bits and compatible with ASCII 127. They use encoding greater than 128 as a leading byte, followed by the second (or even third) after leading byte) character and leading byte are used as the actual encoding. There are many such character sets.GB-2312Is one of them.

The Unicode name is "Universal multiple-octet coded character set", abbreviatedUCs. UCOS can be seen
Here is a brief introduction. (The following content is basically extracted from Python. Core. programming.2ed)
Unicode is a secret weapon that computers can support multiple languages on the planet. Before Unicode, it uses ASCII and ASCII, each English character is stored in a computer in the form of a 7-bit binary number. The value range is 32 to 126. its implementation principle is not mentioned here.
