the compatibility of different languages between the interaction, and ASCII is no longer competent for this task.Unicode Detailed Introduction1. Two bytes easy to produce after ambiguityThe first version of Unicode is a two-byte (16bit) representation of all charactersIn fact, it's easy to say that it's confusing, and we always think that two bytes is two bytes when it is saved in the computer. So any character that is represented by Unicode is saved to two bytes. In fact, this is a mistake.In

version of Unicode uses two bytes (16 bits) to represent all characters. . In fact, this is easy to produce ambiguity. We always think that two bytes represent two bytes stored in the computer. therefore, any character stored in Unicode occupies two bytes. in fact, this statement is incorrect. In fact, Unicode involves two steps. The first step is to define a specification and specify a unique number for all characters. This is completely a mathemati

Unicode encoding, Base: It assigns a unique integer to each character unit of all word systems in the world, which is between 0~1114111 and is called a code point in Unicode terms. and other character encodings are almost no different (for example, ASCII). The difference is that ASCII maps each index to a unique binary representation, but Unicode allows multiple code points with different binary encodings. Different encodings weigh between the number of strings required to store and the speed o

for storage, the size of the text file will be two or three times times larger , it is unacceptable.They result in: 1) There is a variety of Unicode storage methods, which means that there are many different binary formats that can be used to represent Unicode. 2) Unicode cannot be promoted for a long period of time until the advent of the Internet.5.utf-8The popularization of the Internet has strongly demanded the emergence of a unified coding metho

Coding knowledge Summary The earliest encoding is ASCII, which is only 1-127, expressed in one byte. And the first bit of this byte is 0.Later, many countries found that ASCII characters are too few. For example, Chinese characters cannot be expressed. Therefore, every country developed its own extended code, such as gb2312 in China, big5 of Taiwan, Japanese shift-JIS, etc. The extended code in each country is the same, that is, the extended code with the maximum length of

Unicode is commonly known as unified code, universal code, single code, standard universal code. Unicode development is under the responsibility of the non-profit organization unified code Alliance, which is committed to replacing the existing character encoding scheme with the Unicode scheme. Because some solutions often have only limited space and are not applicable to multilingual environments. Unicode is recognized and widely used in the internationalization and localization of computer soft

The so-called ASCII and 16 binary are just conceptual things that are all binary in the computerThe conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the sameASCII is the encoding of characters, almost the encoding of characters on the keyboard. The following is an ASCII and 16-binary table: ASCII and

This is because the character information in string is stored in Unicode encoding. and Java in order to represent the character (note is a single character), there is a char this data type, and his size is fixed 2 8-bit 16 binary number length, that is, 0~65535 ROM. is one of the characters in the corresponding Unicode. If you want to take a string in the Unicode number, you can use GetChars (in
