Each command implementation object encapsulates a client request, corresponding to the buttons on the chassis, a single chassis can have many buttons, which is equivalent to multiple specific command implementation objects. In command mode, the command object does not know how to process the command, and a corresponding recipient object will be used to actually execute the

What is UTF-8?
First, only an integer is allocated to the character encoding table. there are several methods to represent a string of characters as a string of bytes. the two most obvious methods are to store Unicode text as strings of 2 or 4 byte sequences. the formal names of the two methods are UCS-2 and UCS-4, respectively. unless otherwise s
ISO/IEC 10646. Many operating systems, all the latest browsers and many other products support it. The emergence of Unicode standards and the existence of tools supporting it have become the most important development trend of software technology in the world recently.Unicode can be combined with client servers or multi-tier applications and websites to save costs than traditional character sets. Unicode enables a single software product or website to run across multiple platforms, languages, a

appear garbled? It is because the sender and the recipient are using different encoding methods.It can be imagined that if there is an encoding, all the symbols in the world are included. Each symbol is given a unique character code, then the garbled problem disappears. This is Unicode, as its name indicates, which is an encoding of all symbols.Unicode is also a character encoding method. The scientific name for Unicode is "Universal multiple-octet Coded Character Set", referred to as
Again, it is necessary to emphasize that both the historical UCS and today's Unicode, both refer to the coded character set, not the character set encoding. Take a little time to understand this, and then you will find that all the pages, the system, the coding standards of the back and forth between the conversion and so on complex affairs will be clear, extremely easy.

About the Unicode character set(2011-10-20 20:54:03)The initial Unicode encoding is a fixed-length, 16-bit, or 22-byte representation of a character, which can represent a total of 65,536 characters. Obviously, it is not enough to represent all the characters in a variety of languages. The Unicode4.0 specification takes this into account, defines a set of additional character encodings, which are represented by 2 16-bit characters, so that up to 1,048,576 additional characters can be defined, an
of multi-word segments. For example, the Unicode code of the Chinese character is 6c49. When I write a file, do I write 6C in front or 49 in front? If you write 6C in front, it is bigendian. Write 49 in front, that is, little endian. The word "endian" comes from Gulliver Travel Notes. The civil war in the minor people's country originated from the fact that the big-Endian attack or the little-Endian attack were initiated when the eggs were eaten. As a result, there were six rebels, one of the e

In this language environment, there will be no more language coding conflicts, under the same screen, can display any language content, this is the greatest advantage of Unicode.
So how is Unicode encoded? actually very simple.

UTF code
The UTF-8 is to encode the UCS in 8-bit units. The encoding method from UCS-2 to UTF-8 is as follows:
UCS-2 encoding (16-in-system)
UTF-8 byte stream (binary)
0000-007f
0xxxxxxx
0080-07ff
110xxxxx 10xxxxxx
0800-ffff
1110xxxx 10xxxxxx 10xxxxxx
For example, the Unicode encoding of the word "Han" is 6c49. 6c49 between 0800-FFFF, so be sure to use the 3-byte
