Here I briefly talk about the coding problems that are often encountered in front-end HTML and JavaScript daily work.
In a computer, the information we store is expressed in binary code. We know, the on-screen display of English, Chinese characters and other symbols and stored binary code of the conversion, that is, coding.
There are two basic concepts to note, CharSet and character encoding:
CharSet, cha
Programming | coding | who can write code! A few months of programming experience allows you to write "Running applications." Make it easy to run, but coding in the most efficient way requires more effort!
You know, most programmers are writing "run code," not "efficient code." We mentioned earlier in this guide course, do you want to be your company's "Most distinguished professional"? Writing "Efficient
1. Str and bytes
1.1 str is text, Bytes is byte
Text is encoded (utf-8,gbk,gb2312, etc.)BYTE is not encoded
Text encoding refers to how the character uses bytes to represent the organization, and Linux defaults to using UTF-8Bytes 2 can be defined by a B prefix . Python2 and Python3 Coding 2.1 Python2
In Python2, the bytes and STR types are not distinguished, and in Python3 bytes and Str are differentiated, and all operations of STR bytes Support

In the development of the web will often encounter garbled problems, garbled general out now:
1. Written in the JSP file in the Chinese into garbled
2. The Chinese character of the page becomes garbled
3. Background through Request.getparameter () garbled Code of the basic knowledge
Computers can store and transmit information in bytes only, while people need to look at
LZW Coding Algorithm Detailed
LZW (Lempel-ziv Welch) encoding, also known as the string table encoding, is Welch the lemple and Ziv proposed by the lossless compression technology improved compression method. GIF image files are an improved LZW compression algorithm, commonly referred to as the GIF-LZW compression algorithm. The following is a brief introduction to the coding and decoding equations of GIF-
As the title, I use Python to parse the file (the file contains Chinese) and write the other file times incorrectly:

Question: Why do we need reload?

Tomcat will encode the kanji with the default encoding of GET, append to the URL after encoding, and result in the iso8859-1 parameters being garb
Google C + + Coding style definitionThe input parameter is passed in as a value or a const reference, and the output parameter uses a pointer. All input parameters in the form of a reference must be const, which is the form of the const t.such as the following form:void Foo(conststring instring *out);In the following cases, you can use the form of the const t*:* The need for pointers to be empty (i.e. null pointers are justified).* Requires the use of

In the following description, the word "Chinese" is used as an example. We can see that its gb2312 encoding is"D6d0 cec4", Unicode encoding is"4e2d 6587", UTF Encoding is"E4b8ad e69687". Note that the two words do not have iso8859-1 encoding, but they can be represented by iso8859-1 encoding ".
