ArticleSource http://www.ruanyifeng.com/blog/2007/10/ascii_unicode_and_utf-8.html   At noon today, I suddenly wanted to figure out the relationship between Unicode and UTF-8, so I began to look up information online. As a result, this problem

Character encodingAs we've already said, strings are also a type of data, but a special string is a coding problem.Because a computer can only handle numbers, if you are working with text, you must convert the text to a number before processing it.

Because a computer can only handle numbers, if you are working with text, you must convert the text to a number before processing it. The oldest computer was designed with 8 bits (bit) as a byte (byte), so a single word energy-saving representation

This article will briefly describe the concept of character set and character encoding. And some commonly used diagnostic techniques when encountering garbled characters.Background: Character sets and encodings are undoubtedly headache problems for

Character encoding is the cornerstone of computer technology. To be familiar with computers, you must understand a little bit about character encoding. 1. ASCII code We know that in a computer, all information is eventually represented as a

Character encoding: ASCII, Unicode, UTF-8, gb2312   1. ASCII code   We know that in a computer, all information is eventually represented as a binary string. Each binary bit has two states: 0 and 1. Therefore, eight binary bits can combine 256

Currently, various Linux distributions support UTF-8 encoding. The current system's language and character encoding settings are saved in some environment variableslocaleCommand to view: $
