Character encoding Ultimate Note: ASCII, Unicode, UTF-8, UTF-16, UCS, BOM, Endian

Very detailed very good, turn around to study:Reprinted from: http://www.cnblogs.com/lidabo/archive/2013/11/27/3446518.html1, character encoding, internal code, incidentally introduced Chinese character codingCharacters must be encoded before they can be processed by the computer. The default encoding used by the computer is the internal code of the computer. Early computers used 7-bit ASCII encoding, and in order to deal with Chinese characters, prog

BCD and ASCII transcoding-C language implementation

Recently because of the project needs, need to convert the BCD code to the corresponding string, the following is the C language implementation, tested good!Reprint please indicate the source!/*BCD and ASCII code conversion *//******************************************************************* function name: ASC2BCD Function Description: Convert ASCII code to BCD parameter: BCD: converted BCD C

Common ASCII code Comparison table

The most widely used character set and its code in the current computer is the ASCII code (American Standard Code for Information Interchange, American Standard Information Interchange Code) developed by the U.S. National Standards Office (ANSI). It has been set by the International Organization for Standardization (ISO) as a standard, known as ISO 646. Applicable to all Latin letters, ASCII code has 7-bit

Keyboard, game, ASCII code issues

Beginners love to develop small games, such as snakes and Tetris. To develop such games, they must be controlled by keys. Generally, we use the getch () function to receive keys directly, then convert it to the corresponding ASCII code, and compare it with the ASCII code to determine what key the user is pressing, and then perform the corresponding operations based on the key, such as moving and rotating. H

The relationship between the "Python base" character encoding Ascii-gbk-unicode-utf-8

Character encoding because the computer only recognizes 0 and 1, in order to enable the computer to support symbols such as text and letters, convenient and practical operation of the computer so that the character encoding came into being, designed to solve the symbol and human language and computer 0 and 1 to establish a correspondence relationship it is said that the character encoding may be a lifelong regret, Take it out alone. History: Ascii-->u

ANSI, ASCII, Unicode, and UTF-8 encoding

English character with a byte, representing Chinese with two bytes, and Unicode is represented by two bytes, whether it is an English character or Chinese. 2. ASCIIThe data inside the computer is eventually stored in binary form, with each bits (bit) having 0 and 12 states, and 8 bits (bit) combinations called a byte (byte), so a byte can be combined in 256 state, that is, from 00000000 to 11111111.In the 70 's, the American National Standards Association (American Nation Standard Institute, AN

The ASCII decoded table-driven mode of the Tomcat kernel

We know that the Tomcat communication is based on the socket, and the socket on the server side and the client passes the message is not encoded byte stream, each 8 bits constitute 1 bytes, the computer is based on the binary system, which is due to the use of the transistor opening and closing state of 1 and 0, This allows 8 transistors to form a single byte, which is the smallest unit-byte used by the application layer.In the network communication through the socket program, if we do not know

C language programming ASCII American Standard Information Interchange Standard Code Introduction

American Standard Information Interchange Standard Code (American Standard Code for information interchange, ASCII) In a computer, all data is stored and computed in binary representation (because the computer is silly, only the binary values of the 0 and 1 digits are suitable for it). Similarly, 52 letters (including uppercase letters) such as A, B, C, and D, as well as numbers such as 0, 1, and 2, as well as some common symbols (such as *, #, @, et

Unicode and ASCII

Features of 1.ASCIIASCII is an encoding specification used to denote English characters. Each ASCII character occupies 1 bytes, so the maximum number of characters that the ASCII encoding can represent is 255 (00H-FFH). This is not a problem for English, generally only use the first 128 (00H--7FH, the highest bit is 0). The top 1 of the other 128 characters (80H-FFH) are referred to as "extended

ASCII, Ord function usage in MySQL

One, ASCII (STR1) Returns the ASCII code value of the leftmost character of the string str. If Str is an empty string, returns 0. If STR is NULL, return null Example:1. The code is as follows Copy Code Mysql> Select ASCII (' Hi ');+ ————-+| ASCII (' Hi ') |+ ————-+| 104 |+ ————-+1 row in

Analysis of ASCII and Unicode-encoded message writing files

Abstr:] ASCII and Unicode are two common character encodings. Their representation methods are different, so they must be differentiated in the program. Based on the actual development experience of the author, this article analyzes in detail the file Writing Process of ASCII and Unicode character encoding messages, which provides a useful reference for the development of relevant software. Key Words]

The MySQLASCII () function returns the ASCII value of a character.

In mysql, the ASCII function converts characters into ascii code values. the following small series will introduce the usage and examples of ASCII functions in mysql to coders. For more information about coders, see. ASCII (str1) Returns the ASCII code value of the leftmost

Objective: If the password domain

Character-coded notes Ascii,unicode and utf-8_ other synthesis

1. ASCII code We know that inside a computer, all information is ultimately represented as a binary string. Each bits (bit) has 0 and 12 states, so eight bits can combine 256 states, which is called Byte. That is, a byte can be used to represent 256 different states, each of which corresponds to a symbol, or 256 symbols, from 0000000 to 11111111. In the 60 's, the United States developed a set of character coding, the relationship between English ch

Initial understanding of ASCII

ASCII: The United States Standard Information Interchange code, is now the most common single-byte encoding system. Here is a simple understanding of what the code means. Coding is the process by which information transforms from one form or format to another. A conversion convention is required in this process. When all the data in the computer is stored and run, all the information is represented by the binary number (0,1), and what binary data repr

Conversion of ASCII code to 16 binary (table)

The so-called ASCII and 16 binary are just conceptual things that are all binary in the computerThe conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the sameASCII is the encoding of characters, almost the encoding of characters on the keyboard. The following is an ASCII and 16-binary table:

Python standard library: Built-in function ASCII (object)

This function, like the repr () function, returns a printable representation of an object string. When a non- ASCII Code is encountered, it is output \x,\u , or \u characters . the repr () in Python version 2 is the equivalent function. Example:#ascii () function print (ASCII (ten), ASCII (9000000),
