processed by the Unicode function. It can be seen that using Unicode to call APIs will be much faster. Similarly, the API functions that return strings perform the same conversion. Two APIs in the system take createfile as an example. As defined below # Ifdef Unicode # Define createfilew createfile # Else # Define createfilea createfile # Endif When we call createfile, the system selects a normal function based on whether you want Unicode. When you call createfilea Call createfilea ---> conve

Brief description: ANSI is a character code that, for the computer to support more languages, typically uses 2 bytes of the 0x80~0xff range to represent 1 characters. Uincode (Unified code, universal code, single Code) is an industry standard in the field of computer science, including character set, encoding scheme, etc. Unicode is created to address the limitations of traditional character encoding schemes, which set a unifor

In Windows Mobile and Windows, the string is Unicode. Therefore, when developing native code, pay special attention to String Conversion. Below is a simple String Conversion method. Record it for search.

ANSI X9.8 Standard pin xor pan get pin BlOCKBefore I saw a few introductions, the ANSI is said to be 16 bytes, really rip, all kinds of fraught, the real ANSI algorithm is actually 8 bytes, the specific format is as follows:(1) ANSI X9.8 Format(without master account information)PIN (Personal identification number Pers

solve the Text wrap problem. Character encoding: ======================== Text is a human language. For computers, the language is only 0 and 1. Therefore, saving characters in a computer involves character encoding. There are manyArticleDifferent from the blog's character encoding method, it will not be referenced here. Key points I understand: ASCII: ANSI The original computer storage is limited. The character storage uses 8-bit ASCII c

Use the C function to convert Unicode and ANSI text Char schar [max_path];Const wchar [] = l "my friends ";// Convert the Unicode string wchar to an ANSI string, save it to schar, and return the ANSI string size. If it fails,-1 is returned.Wcstombs (schar, wchar, max_path ); In this case, the system always returns-1. Later, I was reminded that you must set i

To enable the computer to support more languages, we usually use 0x80 ~ 2 bytes in the 0xff range to 1 character. For example, in the Chinese operating system, the byte [0xd6, 0xd0] is used for storage. Different countries and regions have developed different standards, resulting in respective coding standards such as gb2312, big5, and JIS. These two bytes are used to represent the extended Chinese character encoding methods of a single character. They are called

To enable the computer to support more languages, you typically use the 0x80~0xff range of 2 bytes to represent 1 characters. For example: Chinese characters ' in ' in the Chinese operating system, using [0xd6,0xd0] These two bytes of storage. Different countries and regions have developed different standards, resulting in GB2312, BIG5, JIS and other coding standards. These use 2 bytes to represent a character of a variety of Chinese character extension encoding, called
