ASCII has only one, and most MBCS (including GB-2312) have only one. For example, the "connected" two-word Unicode standard encoding UTF-16 (big endian) is: DE 8F 1 A 90 and its UTF-8 encoded as: E8 BF 9E E9 9A Finally, when a software opens a text, the first thing it does is decide what kind of text is used Which encoding of the character set is saved. The software has three ways to determine the character set and encoding of text: The most standard way is to detect the beginning of the textA

they sat together and shoot their heads to come up with a method: all the characters in the language are represented by the same character set, this is Unicode. The original Unicode standard UCS-2 uses two bytes to represent a single character, so you can often hear Unicode uses two bytes to represent a single character. But soon some people think that 256*256 is too small, or not enough, so there is a UCS

The transitions between them can be implemented by the program.Under the Windows platform, one of the simplest ways to convert is to use the built-in Notepad applet Notepad.exe. After opening the file, click "Save as" on the "File" menu, you will get out of a dialog box, at the bottom there is a "coded" drop-down bar.There are four options: Ansi,unicode,unicode big endian and UTF-8.1) ANSI is the default encoding method.

The character set and coding of WML WML uses the character set of XML, the universal Character set iso/iec-1062, or the unified character encoding standard Unicode 2.0.

For our programmers, Emoji brings a lot of problems What is the length? How do i show consistency across various platforms? Solving these problems cannot be separated from Unicode characters.When we talk about Unicode, what are we talking about?

, the problem came out. Let's take China as an example. There are tens of thousands of Chinese characters. What should I do?The existing 8 bits one-byte system is the foundation and cannot be damaged. It cannot be changed to 16 bits or the like. Otherwise, the change is too large and you can only take another path: multiple ascii characters are used to represent one other Character, that is, MBCS (Multi-Byte Character System, Multi-Byte Character System ).With the concept of MBCS, we can represe
