What is ANSI and what is Unicode? In fact, this is the two different coding standards, ANSI characters in 8bit, and Unicode characters in 16bit. (for characters that say ANSI holds English characters in single-byte, double-byte for Chinese, and Unicode, both English and Chinese characters are stored in double-byte) Unicode

This article describes how to use Unicode encoding in Python2.x. Unicode in Python3 is used as the default encoding, unicode in the Python2 version, which is still widely used, is a place to pay attention to during use. For more information, see Unicode and Python, however, I plan to write something about them to facil

I did not notice that the differences in file encoding will cause so many problems. I have searched a lot of information before I started, and I have added many of my predecessors to my blog. I would like to pay tribute to them here!I will not talk about the principle of ANSI and Unicode encoding here. I will mainly talk about how to r
Handle text correctly, especially if Unicode is handled correctly. It's a cliché, sometimes even a seasoned developer. Not because the problem is difficult, but because of the text in the software, the developer does not correctly understand some key concepts and their presentation methods. Search for Unicodedecodeerror related questions on StackOverflow, and you can see that many people have this misunderstanding. The concepts of these errors can be

The issue of Chinese coding needs to be discussed in detail, which is not covered by this note. It only points out that although all are represented by a number of bytes, the encoding of the GB class has nothing to do with the Unicode and UTF-8 of the latter text.

As mentioned in the previous section, there are many ways of coding in the world, and the same binary number can be interp
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 symbols, from 0000000 to 11111111.

historical annotations. Before Unicode, there was a separate character encoding system for each language, and each system used the same number (0-255) to represent the characters of the language. Some languages (like Russian) have several conflicting criteria for how to represent the same characters, and others (like Japanese) have too many characters and require multiple character sets. It is difficult to document communication between systems becaus

Each step of the move to adjacent numbers on the row below.For example, given the following triangle[ 2], [3, 4], [6,5, 7], [4,1, 8,3]]The minimum path sum from top to bottom 11 is (i.e., 2 + 3 + 5 + 1 = 11).Note:Bonus Point If you be able to does this using only O(n) extra space, where n is the total Number of rows in the tria
In the past two days, I took the time to summarize/sort out the actual encoding methods and usage of various encodings in Java applications. I will record them here for future reference. In order to form a complete understanding and in-depth understanding of text encoding, in order to deal with various problems encountered during Java development, especially the garbled problem, I think it is better to make up a series to describe and analyze, including three articles: First Article: Java charac

The history of the character set mentioned in this article is a brief explanation of the relationship between Unicode and Utf-8, briefly summarizing:Utf-8 and Utf-16, Utf-32 is a class, the realization of the function is the same, but the most widely used utf-8, but Unicode and utf-8 is not the same class,

The biggest advantage of Unicode is that there is only one character set. In other words, a program using Unicode character encoding can be compiled in any country's compiling environment without being considered garbled, it can also display characters normally in the editing environment of any language, rather than garbled characters. Does
