ASCII values вЂ‹вЂ‹of 8, 9, 10 and 13 are converted respectively For backspace, tabulation, line feed and carriage return characters.

communication special characters: SOH (head of text), EOT (end of text), ACK (acknowledge), etc. Among them:Д пЅћ31 and 127 (33 in total) are control characters or communication special characters (the rest are displayable characters), such as control characters: LF (line feed), CR (carriage return), FF (page feed), DEL ( Delete), BS (backspace), BEL (bell), etc.

It uses 7-bit binary numbers (the remaining 1 bit is 0) to represent all uppercase and lowercase letters, numbers 0 to 9, punctuation marks, and special controls used in American English Character.

Standard ASCII code is also called basic ASCII code. The ASCII code uses a specified 7-bit or 8-bit binary number combination to represent 128 or 256 possible characters. In the computer, all data must be represented by binary numbers when storing and computing (because the computer uses high and low levels to represent 1 and 0 respectively), for example, such as a, b, c, d 52 letters (including uppercase) and numbers such as 0, 1, and some commonly used symbols (such as *, #, etc.) should also be represented by binary numbers when stored in a computer, and which binary numbers are used to represent which symbol, Of course, everyone can agree on their own set (this is called encoding), and if everyone wants to communicate with each other without causing confusion, then everyone must use the same encoding rules, so the relevant United States standardization organization introduced ASCII The encoding uniformly stipulates which binary numbers are used for the above-mentioned common symbols. Detailed explanation of various common codes UTF-8 refers to the encoding method of characters.Дў. Through this number and character mapping table, we can convert a binary number into a character.Д¬haracter encoding method: For example, for the number 21475 that should be 'mouth', should we use/u5k3e3 or %E5%8F%A3? This is determined by the character encoding. Different tables have different mapping relationships, such as ascii, Gb2312, Unicode (note that UTF-8 is not a character set). The character only represents a symbol.Д¬haracter set: It is a table of the mapping relationship between a certain symbol and a certain number, that is, it determines that 107 is the 'k' of koubei, and 21475 is the 'kou' of word of mouth. 'A' is a character, and 'в‚¬' (a symbol of the common currency of Germany, France and many other European countries) is also a character. It has no fixed shape (it may be a glyph), and it has no value. Characters, character set and character encodingД¬haracter: A character is the smallest abstract text unit.
