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
The problem of character encoding seems to be very small, often overlooked by technical staff, but it can easily lead to some puzzling problems. Here is a summary of the character encoding of some of the popular knowledge, I hope to be helpful to
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
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
ASCII code table
The ASCII code can be roughly divided into three parts.The first part is ASCII non-printable control characters;The second part is: ASCII printing characters;The third part is: Extended ASCII print characters.Part 1: ASCII
ASCII (American Standard Code for information interchange) is a computer coding system based on Latin letters. It is mainly used to display modern English and other Western European languages. It is the most common single-byte encoding system today
Currently, the most widely used character set and Its Encoding in computers are American Standard Code for information interchange (American Standard Code for information interchange) developed by the National Bureau of Standards (ANSI ), it has
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
The code is as follows
