Unicode: Wide-Byte Character Set1. How to obtain the number of characters in a string that contains both single-byte and double-byte characters?You can call the Runtime Library of Microsoft Visual C ++ to contain the function _ mbslen to operate multi-byte strings (including single-byte and dual-byte strings.Calling the strlen function does not really know how many characters are in the string. It only tells you how many bytes are before the end of 0.

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. One, ASCII code We know that inside the computer, all information is ultimately a binary value. Each bits (b

1. Under Unicode encoding, the characters in CString are declared as wide words and should be obtained using the following method char*CString Cstrip = strIp; // Convert CString to char* under Unicode int n = cstrip.getlength (); int len = WideCharToMultiByte (CP_ACP,0, Cstrip,cstrip.getlength (), NULL,0, null,null) ; Char New Char [len+1]; WideCharToMultiByte (CP_ACP,00;View Code2.

The project encountered a Python coding problem, through the network to get a string with ' \u ', to understand that this is a Unicode code, corresponding to a number of Chinese, so try to use the online "Python Unicode to Chinese" method to do encode and decode, The result is not good. Later found to do decode when you can bring a ' unicode-escape ' option, plus

These days many of the Winnt servers have been hacked, especially at home. The following is a summary of some specific examples. Following this type of vulnerability to find nearly a year, more than a year ago in the foreign hacker website has a similar article, but Was not a lot of people pay attention to it at that time. , many of the anti-NATO hacking wars have been used in the following examples. But until the discovery of the unicoude loophole, the Black NT computer became a fool. Below I p

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

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. The contents of this sp
