scheme, there are two problems to solve:A. How bytes are grouped, such as 8 bits or a set of bits, which is also known as the encoding unit.B. The mapping between the encoding unit and the character. For example, in ASCII code, the decimal 65 is mapped to the letter A.ASCII code is one of the most popular coding systems of the last century, at least in the west. Shows how the encoding units in the ASCII code are mapped to characters.The history of ch

For coding, each yard may have its own set of styles, many people may not care about the coding style at all, because the final compiler compiled by the target code will not be affected. But in the development of a large project, the most time-consuming cost is always the communication between the developers. Keeping your coding style consistent can greatly impro

In fact, PHP development in the Chinese code is not as complex as imagined, although the location and solve the problem is not confine, all kinds of operating environment is not always, but the principle behind is the same.Understanding Character Set knowledge is the basis for solving character problems.The problem of Chinese coding in PHP programming has plagued a lot of people, the cause of this problem is actually very simple, each country (or regi

The following list of Python2 frequently encountered several problems and explanations.#-*-Coding:utf-8-*-Python2 by default in ASCII encoding, but in the actual coding process, we will use a lot of Chinese, in order to not include the Chinese program error, but also in order to comply with international conventions, we generally set our file encoding to UTF-8 format.There are many formats for setting the encoding, as long as the declaration of the fi

tutorials on the Internet to explain how to use PHP to add a fancy feature to development applications, but most of them do not cover how to ensure the security of these features, this prevents applications from being vulnerable to attacks. Therefore, PHP applications with rich functions are generally not developed in a secure way. Train your developers to write code with secure thinking, which is more important than the choice of language. CERT (Computer Emergency Response Team, Computer Emerg

In the previous article mentioned in the BOM header, actually involved in the text encoding problem, the BOM header is appearing under Windows with a text editor after writing the file, in accordance with the UTF-8 format to save the file and we are in the editing of PHP script is usually in utf-8 format to save the script file, in this case, We can't find the BOM header. However, if we save PHP script files according to GBK code, we can easily find the existence of BOM head, the reason is simpl

Arithmetic Coding plays an important role in image data compression standards (such as JPEG and JBIG. In arithmetic encoding, messages are encoded using real numbers ranging from 0 to 1. Arithmetic Coding uses two basic parameters: the probability of a symbol and Its Encoding interval. The probability of the source symbol determines the compression encoding efficiency, and also determines the interval of th

To summarize, you can handle Unicode characters from the python1.6 start. one, several common coding formats.1.1, ASCII, expressed in 1 bytes. 1.2, UTF-8, with 1 to three bytes, representing ASCII code for only 1 bytes, ASCII encoding is a subset of UTF-8. 1.3, UTF-16, in 2 bytes, in Python, the meaning of Unicode is UTF-16. Second, the Python source file encoding and decoding, we write the Python program from the production to the implementation of

Introduction to Huffman coding Huffman encoding is the binary encoding pairing of characters and characters, which is divided into encoding and decoding to compress the binary data length of characters. We know that character storage and transmission are binary (the computer only knows 0/1), then there is the mapping relationship between the character and the binary. Characters belong to character sets (Charset), characters need to be encoded (encode
