Some time ago, in the participating projects encountered a Unicode and GB transcoding failure problem, some of the characters are not commonly used encoding has been translated into the "??", the Chinese characters did not show up, so they did some research on the related problems and finally solved the problem. Now, combining the previous two Unicode and GB fundamentals, this paper introduces the method of
The coding aspect has always been not very high, so it is not known about Unicode and UTF-8.
Recently accidentally turned to a UTF-8 article, feel the explanation of the very complex, so just thought to write a simple and understandable.
Let's begin by explaining some of the coding schemes that are now commonly used:1, in China, the most commonly used in the mainland is GBK18030 code, in addition to the gbk,gb2312, the relationship between these sev

Q How to display Unicode strings
A
If the program defines _ Unicode macro, directly use
Wchar * STR = l "unicodestring ";
Textout (0, 0, STR );
Otherwise, the conversion type is required.
# Include Wchar * STR = l "unicodestring ";
Bstr_t str1 = STR;
Textout (0, 0, (char *) str1 );

shift_]is, and Korea has made Korean into EUC-KR.Countries have national standards, there will inevitably be conflicts, the result is that in multi-language mixed text, the display will be garbled.The Unicode standard is also evolving, but it is most commonly used to represent a character in two bytes (4 bytes If a very remote character is used).Unicode is supported directly by modern operating systems and
Handle text correctly, especially if Unicode is handled correctly. It's a cliché, sometimes even a seasoned developer. Not because the problem is difficult, but because of the text in the software, the developer does not correctly understand some key concepts and their presentation methods. Search for Unicodedecodeerror related questions on StackOverflow, and you can see that many people have this misunderstanding. The concepts of these errors can be
Using today's time, we studied the differences between ANSI and Unicode, and then wrote down my findings for future reference.
The most common application of ANSI encoding is in the Notepad program in Windows, when creating a Notepad, the default save encoding format is ansi,ansi should be considered a compression encoding, when encountering standard ASCII characters, a single-byte representation when encountering non-standard ASCII characters (such a

Unicode encoding is the basis for UTF-8 and gb series encoding (gb2312, gbk, and gb18030) Conversion. although we can also directly create a UTF-8-to-these encoding table, but few people will do this, because the variable encoding of UTF-8 is uncertain, so the general use of unico

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.

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.

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.

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
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.
