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
In the Python language, uincode string processing has always been a confusing problem. Many python enthusiasts often have trouble figuring out the difference between Unicode, UTF-8, and many other encodings. This article describes the knowledge of the Chinese processing of Unicode and Python. Let's take a look at the little series.

It is a headache to deal with Chinese in python2.x. On the Internet to write this aspect of the article, the test time is not neat, and will be a bit wrong, so here intend to summarize an article.
I will also study in the future, and constantly modify this blog.
This assumes that the reader has a basic knowledge of the encoding, and this article is no longer introduced, including what is utf-8, what is Unicode, and what is the relationship between t
UNICODE: Wide-Byte Character Set 1. How to obtain the number of characters in a string that contains both single-byte and double-byte characters?
You can call the Runtime Library of Microsoft Visual C ++ to contain the function _ mbslen to operate multi-byte strings (including single-byte and dual-byte strings.
Calling the strlen function does not really know how many characters are in the string. It only tells you how many bytes are before the end
1: first, change the project attribute to a multi-byte character set.2: For all l "strings", remove L, or change to => _ T ("string ")PS1: _ t is an automatically replaced macro. It can be replaced with something different based on the Compilation conditions.PS2: to use _ t, you must first include the 3: replace all wchar with tchar4: replace all Unicode functions with non-Unicode functions eg _ wsplitpath_

In python, uincode string processing has always been a confusing problem. Many Python enthusiasts are often confused about the differences between Unicode, UTF-8, and many other encodings. I used to be a member of this "brainstorming group", but after more than half a year of hard work, I finally figur
, from the location code to the inner code, you need to add A0 on the high and low byte respectively.In DBCS, GB internal code storage format is always big endian, that is, high in front.The highest bit of the two bytes of the GB2312 is 1. But the code bit that meets this condition is only 128*128=16384. So the low-byte highest bits of GBK and GB18030 are probably not 1. However, this does not affect the parsing of DBCS character streams: When reading a DBCS character stream, you can encode the

Q How to display Unicode strings
A
If the program defines _ Unicode macro, directly use
Wchar * STR = l "unicodestring ";
Textout (0, 0, STR );
Otherwise, the conversion type is required.
# Include Wchar * STR = l "unicodestring ";
Bstr_t str1 = STR;
Textout (0, 0, (char *) str1 );

Program Users in non-English countries, such as China, Japan, Eastern Europe and the Middle East, must be familiar with Unicode character sets.

CodingA string is a data type, but a particular string is a coding problem.Because a computer can only handle numbers, if you are working with text, you must convert the text to a number before processing it. The oldest computer was designed with 8 bits (bit) as a byte (byte), so a single word energy-saving representation of the largest integer is 255 (binary 11111111 = decimal 255), if you want to represent a larger integer, you must use more bytes. For example, two bytes can represent the larg
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

The first thing to figure out is that in Python, string object and Unicode object are two different types.String object is a sequence consisting of characters, and Unicode object is a sequence of Unicode code units.Character in string are encoded in a variety of ways, such as Single-byte ASCII, Double-byte GB2312, and so on, such as UTF-8.

If you are writing programs that target non-English-speaking users, such as China, Japan, Eastern Europe, and the Middle East, then you must be familiar with the UNICODE character set. Especially if you are writing a program for users in these countries and regions with Visual C++/MFC, if you want your application to have a wider audience, you must consider code UNICODE compatibility, wh
