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.

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),

ASCIIThe ASCII code is a 7-bit code with the encoding range of 0x00-0x7f. The ASCII character set includes English letters, Arabic numerals, punctuation marks, and other characters. 0x00-0x20 and 0x7f contain 33 control characters.The system that only supports ASCII Code ignores the maximum bit of each byte and considers the low 7 bits as the valid bit.

The value range of the ASCII code is 0 ~ 127, which can be expressed in 7 bits. C LanguagecharThe variable size is defined as one byte. If the ASCII code is stored, only seven characters are used, and the value is 0. The following is an ascii code table: Figure A.1. ASCII code table In most computers, one byte is 8 b

First, let's briefly talk about the history. The ASCII code was first developed by Americans. What is it? We know that the computer only knows 0 and 1. If we want the computer to recognize characters other than 01, for example, 'A', we must first tell the computer that '123' is 'A '. Just like the moss password, it means SOS ). The so-called character encoding means to intercept with the computer and agree with the computer What character a series of

In xcode, files are saved in utf8 format. Therefore, the variable object is also saved in utf8 format. Different Languages have different utf8 codes. English utf8 codes are the same as ascii codes. The number of UTF-8 encoded bytes for each character in different languages is different, and the bytecode is also different. For English characters, It is very convenient to view its ascii code. It is its

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 been set as an international standard by the International Organization for Standardization (ISO), known as the ISO 646 standard. It is applicable to all Latin characters, including 7-digit ASCII code and 8-di

For example, the SPACE is 32 (Binary 00100000), and the uppercase letter A is 65 (Binary 01000001 ). These 128 symbols (including 32 control symbols that cannot be printed) only occupy the

ASCII codeWe know that inside the computer, all the 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 a byte. In other words, a byte can be used to represent 256 different states, each of which corresponds to a
