specific Symbol correspondence table, may query unicode.org, or the specialized Chinese character correspondence table. The Unicode character set divides all characters into 17 levels (Plane) on a per-use basis, with 216 = 65,536 character code space at each level. The No. 0 level of BMP (basic Multilingual plane base multilingual plane), basically covers all the characters used in today's world. Other dimensions are either used to denote some ancient words or to be extended. The Unicode chara
expressed in the format of U-XXXXXXXX, while BMP encoding is usually usedIn the format of U + XXXX, X is a hexadecimal number. At the same time that ISO developed the UCs, another joint manufacturer organization was also working on developing such encoding, known as Unicode. Later, the two jointly developed a unified encoding, but released their respective standard documents, therefore, the UCS encoding an
Unicode is commonly known as unified code, universal code, single code, standard universal code.
Unicode development is under the responsibility of the non-profit organization unified code Alliance, which is committed to replacing the existing character encoding scheme with the Unicode scheme. Because some solutions often have only limited space and are not applicable to multilingual environments.
Unicode is recognized and widely used in the internationalization and localization of computer soft
principles of Unicode version 2 are the same, I will not talk about it much.
As mentioned above, we need to know the specific encoding method and determine the mark at the beginning of the text. below is the mark at the beginning of all codes.

character set, which is Unicode.The original Unicode standard UCS-2 uses two bytes to represent one character, so you can often hear the assertion that Unicode uses two bytes to represent a character. But soon some people think 256*256 too little, or not enough, so there is a UCS-4 standard, it uses 4 bytes to represent a character, but we use the most is still UCS

But soon some people think 256*256 too little, or not enough, so there is a UCS-4 standard, it uses 4 bytes to represent a character, but we use the most is still UCS-2. The UCS (U
is a language developed by all the countries in the world if we describe all kinds of text coding as dialects of different places.
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.
is to encode all the text in the world in 2 bytes. You might ask, 2 bytes can represent up to 65,536 encodings, is it enough?

instance, refer to the Android Asset packaging Tool (AAPT).Note that if you are using the Eclipse IDE and you have already installed the ADT plugin, you do not need to use ADB (or AAPT) to install the emulator/device application directly. Otherwise, the ADT plugin handles the packaging and installation of the application on your behalf.Forwarding Portyou can use the forward command to forward any port-a specific host port for one emulator/device instance forwarding requests to another different
/device instance to another port. The following demonstrates how to establish forwarding from host port 6100 to simulator/device port 7100.
adb forward tcp:6100 tcp:7100
Similarly, you can use ADB to create an abstract Unix domain interface. The process is as follows:
adb forward tcp:6100 local:logd
