Label:When doing metering pump, use MySQL to store data, build table hisruninfo (metering pump history running data table).Table format for UTF8, check the database is also UTF8When importing the Hisruninfo.sql file, there was no error and the table could be built, but when importing another Data1.sql file that inserted the data, an error occurred--Chinese characters were not recognized.Nothing wrong with inserting contentLater, when you save Data1.sql as a. sql file, the bit UTF8 can be importe

The network has a lot of learning materials in the form of web pages, collected very practical, but a lot of information in different language coding, there are GB2312, BIG5, UTF-8, and so on, some in the relevant page marked with the language code is OK, if there is no mark, web customers open the appropriate page, The browser may return a heap of garbled characters to the user. The Apache configuration file provides a addcharsetdefautl parameter for the server to return the page to the custome

A 4-bit binary number is used to represent the 0~9 of the 1-bit decimal number, which is called the BCD code, which is the 10 digital. binary-coded decimal, or BCD, is called BCD or two-decimal code, also known as the binary number of binary numbers. is a binary encoded form of a binary coded decimal code.Defining the BCD code this type of encoding uses four bits to store a decimal digit, making the conversion between binary and decimal fast. This cod

When operating files in Windows in Linux, garbled characters are often encountered. For example, C \ c ++ written in Visual StudioProgramIt needs to be compiled on the Linux host, and the Chinese comments of the program are garbled. What is more serious is that the compiler on Linux reports an error due to encoding. This is because the default file format in Windows is GBK (gb2312), while Linux is generally a UTF-8.

Python Encoding Problems, python Encoding I. Encoding history: 1. ASCII (mainly used to display modern English and other Western European languages. It can only be expressed in 8 bits (one byte), that is, 2 ** 8 = 256-1. Therefore, an ASCII code can contain up to 255 characters. 2. In order to process Chinese characters, the programmer designed GB2312 for simplif
