What are binary files? What is ASCII? What is the difference between text files? An ASCII file is also called a text file. When a file is stored on a disk, each character corresponds to one byte and is used to store the corresponding ASCII code.For example, the storage format of 5678 is 5 6 7 8.Binary files are stored in binary encoding.For example,

Python standard library: built-in functions: ascii (object), pythonascii Like the repr () function, this function returns a printable string representation of an object. When a non-ASCII code is encountered, the \ x, \ u, \ U, and other characters are output. It is equivalent to repr () in Python 2. Example: # Ascii () function print (

Turn it off and then turn it back on to solve the problem2:python non-ascii character bug when using Chinese annotation in the

Character encoding notes: ASCII, Unicode and UTF-8 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 is more complicated than I thought. After lunch, we can see that the problem is fixed at AM. Below are my notes, mainly used to sort out my own ideas. However, I try to make it easy to understand and hope it can be useful to other friends. After all, charact

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 states, which is called a byte ). That is to say, a single byte can be used to represent 256 different States. Each State corresponds to one symbol, that is, 256 symb

During some text processing recently, we found that character encoding is a headache, and conversion between various encodings often causes garbled characters, therefore, Perl and C ++ are respectively used to write auxiliary conversions.ProgramTo help some friends. First, I have a general understanding of common character encoding. The initial character encoding was the American standard information interchange code (ASCII), which was still in the
