This article briefly introduces the development history of Unicode and JavaScript. For more information, see 1. What is Unicode? Unicode comes from a very simple idea: to include all the characters in the world in a set, as long as the computer supports this character set, it can display all the characters and there will be no garbled characters. It starts from

This article mainly introduces how the JavaScript language supports the Unicode Character Set. For more information, see what I will share with you next month, and the support of the JavaScript language. The following is the lecture for this sharing. 1. What is Unicode? Unicode comes from a very simple idea: to include all the characters in the world in a set

Unicode programming using C ++ The support for wide characters is actually part of the ansi c standard, used to support multi-byte expression of a character. The width character is not exactly the same as the Unicode character. Unicode is only a type of width character encoding. 1. Definition of wide characters In ANSI, the length of a character (char) i

Brief introduction Today's applications are often designed for international use. These applications may need to handle strings in different languages. Unicode is a language-independent character representation standard. Because the Java programming language already uses Unicode internally to represent characters, the development of internationalized applications is much easier. However, you cannot consid

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 represente

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. For specific details, refer to Wiki: http://zh.wikipedia.org/wiki/U

When we spend most of our time applying existing applications Program Port to Microsoft Windows CE. Generally, this plan is not too difficult. We started with Microsoft Win32 Code Of course, Windows CE is based on Win32 application interfaces (APIS. It is advantageous that our application (Raima Data Manager) has easy-to-use interfaces and contains a library consisting of approximately 150 sub-functions written in C, it can be used to create, manage, and access databases.

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

character. Therefore, it can be expressed at most theoretically. 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 pointed out that although all characters represent one symbol in multiple bytes Unicode is irrelevant to the UTF-8. 3. Unicode As mentioned in the previous section, there are multiple encoding meth

1.1. Question ProblemYou need to deal with data, doesn ' t fit in the ASCII character set. You need to handle data that is not suitable for the ASCII character set. 1.2. Resolve SolutionUnicode strings can be encoded in plain strings in a variety of ways, according to whichever encoding you choose: Unicode strings can be encoded in a number of ways as normal strings, according to the encoding you choose (encoding): 1 #将

VarThe following methods are commonly used in the conversion of such data to Chinese issues.1. Eval parsing or new Function ("' + str + ')" ()// "I am a Unicode encoding"2.

ASCII is a character set, including uppercase and lowercase English letters, numbers, and control characters. It is represented in one byte and ranges from 0 to 127. Because ASCII characters are very limited, each country or region puts forward its own character set on this basis. For example, gb2312, which is widely used in China, provides encoding for Chinese characters, it is expressed in two bytes. These character sets are incompatible with each other. The same number may indicate diff

VC ++ 6.0 supports Unicode programming, but the default value is ANSI. Therefore, developers can easily write Unicode-Supported Applications by slightly changing the coding habits. Using VC ++ 6.0 for Unicode programming mainly involves the following tasks: 1. Add Unicode and _ Uni
