Before this time, I always believe building the program with Unicode or non Unicode flag only effect the programatic side, and won't effect the system behavior. the problem arose with mixing usage of Multi-byte and Unicode Character Set functionalities underThe Unicode base. such as if the

About IdleIn fact, we have to know about it first:Inside Python, the default character encoding is, according to the operating system, most of us are the Chinese system of Windows, the default is GBK encoding.And in the idle, the direct input Chinese characters, actually is the GBK code.The design of strings in 4.PythonThe main is: Python 2.x in STR and

Last month, I shared a detailed description of the Unicode Character Set and the support of the JavaScript language. The following is the lecture for this sharing.
1. What is Unicode?
Unicode comes from a very simple idea: to include all the characters in the world in a set, as long as the

Because the Windows low-level processing string is handled in Unicode, the project for Unicode is now commonly used when developing software with VC.
In Unicode engineering, reading and writing text files can have a rather tang

The project encountered a Python coding problem, through the network to get a string with ' \u ', to understand that this is a Unicode code, corresponding to a number of Chinese, so try to use the online "Python Unicode to Chinese" method to do encode and decode, The result is not good. Later found to do decode when you can bring a ' unicode-escape ' option, plus

These days many of the Winnt servers have been hacked, especially at home. The following is a summary of some specific examples.

0xa1a1-0x7e7e. After undefined areas are removed, the actual encoding range is 0xa1a1-0xf7fe.The EUC-CN can be understood as an alias for gb2312, which is exactly the same as gb2312. The location code should be considered as the definition of Character Set, defining the included characters and character location, while gb2312 and EUC-CN are the encoding of this character set in the actual computer environment. Hz and iso-2022-cn are two types of codes corresponding to the location code characte

In projects, some symbols are sometimes added to some controls (such as Button and TextView), as shown in:
In this case, images can be displayed, but these can be directly displayed using Unicode codes.
The code for the four icons is as follows:
Unicode is implemented in a different way than encoding.The Unicode encoding of a character isOKBut in the actual storage and transmission process, because the design of different system platforms is not necessarily consistent, and for the purpose of saving space, UnicodeThe encoding implementation methods are different..

One, byte, and UnicodeThe Java kernel is Unicode, even the class file, but many media, including file/stream, are saved using a byte stream.So Java wants these bytes to flow through the line transformation. Char is Unicode, and byte is a byte. The functions of Byte/char in Java are in the middle of Sun.io's package. Where the Bytetocharconverter class is in dispatch, can be used to tell you that you use the
Unicode stringThe string also has an encoding 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), 0-255 is used to denote uppercase and lowercase letters, numbers, and some symbols, which
ObjectiveSometimes the return value from the interface is encoded in a format similar to "%u4e0a%u6d77%u60a0%u60a0", not the Unicode encoding in Python.The Unicode encoding inside Python should be this format: \u4e0a\u6d77\u60a0\u60a0Unicode encoding-python21. First look at the Unicode encoding for Python: \u60a0, this is the beginning of the \u, the English is l
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
