The source file is encoded as ASCII by default, so if you do not show what encoding the current code is written with, Python will parse it with ASCII, and if there is UTF-8 encoding in the source file, it will be an error because ASCII cannot translate UTF8 encoding.# file test.py save a='a'b=' good ' using UTF8After running' \xe5 ' in

"WCF4.0 new Feature Experience", a new series of "WCF Service Programming design specification." The main focus of this series is on designing WCF services, and WCF coding specifications. Here I will translate some WCF service design related information, share it with you, and provide the original English download. "1" Preamble: This series should be more practical, for most of the technical staff to use WCF or the company is more important content,

VBScript Coding Conventions Coding conventions are some of the recommendations that help you write code using Microsoft Visual Basic scripting Edition. The encoding convention contains the following: Naming conventions for objects, variables, and procedures Annotation conventions Text formatting and indenting guides The main reason for using a consistent coding c

If you want to be an excellent programmer, good code is important, how can you write good code? In this article we will give you some PHP coding specifications and recommendations. Coding specifications PHP code files must start with the PHP code files must be encoded with UTF-8 without a BOM. Example sublime, setting increased, "show_encoding": True The number of characters p

Character Set and character encodingThe information stored in the computer is represented by a binary number, and the characters we see on the screen, such as English and kanji, are the result of binar

Entropy coding is the encoding process by entropy principle without losing any information. Entropy is the average amount of information (measurement of uncertainty) of the source. Common entropy codes are: Shannon (Shannon) encoding, Huffman (Huffman) encoding and arithmetic coding (arithmetic coding). In video coding

basic knowledge of vim coding:1, there are 3 variables:encoding : This option makes the text used for buffering ( the file you are editing ) , registers, Vim script file and so on. You can think of the "encoding" option as a setting for the internal operating mechanism of Vim. fileencoding : This option is Vim the type of encoding used when writing to a file , which is the use of set fileencoding in Vim to view. termencoding : This option represents t

Four ways to make PHP coding easierDespite the current PHP language has built its own software culture, but to find its maddening shortcomings is definitely not difficult. We have listed in previous articles The 12 worst features that the language is most difficult for developers to accept.But over the past few years, PHP has undergone a series of changes-from the language itself to the relevant ecosystem to the support of the developer community-that

ASCII code We all know that ASCII code, a total of 128, with a byte of low 7-bit, 0-31 is the control character Furu space, enter, delete 32-126 is the print characters, can be entered through the keyboard and can be displayed.

PDU Coding Rules Currently, text and PDU (Protocol Data Unit) are commonly used for sending short messages. Use text mode to send and receive short message code simple, easy to achieve, but the biggest drawback is not to send and receive Chinese text messages, and PDU mode not only support Chinese text messages, but also send English text messages. PDU mode send and receive SMS can use 3 kinds of encoding: 7-bit, 8-bit and UCS2 encoding. 7-bit encod

Java and JavaScript Base64 encoding When developing Java Web applications, it is possible to use Java for BASE64 encoding on the server side, while the client can decode it with JavaScript. This requires consistency of Base64 coding mechanisms on both sides. Using BASE64 encoding, you may encounter a variety of strange situations, and even suspect that the code has bugs. But that's not really the case. Base64 in theory is not a s
