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?
Most of th
Thanks to the convenient assembly and scalability of PCs, the popularity of computers has been accelerated to a certain extent, and manufacturers of computer accessories have naturally made great contributions to this. However, because the computers we use (especially compatible computers) are a combination of products produced by different manufacturers, there will inevitably be "friction" between them ". This is what we usually call incompatibility. The so-called "compatibility" word also come
four-core power plug at the power output end is inserted at the clip seat.
4-core power connection: In addition to connecting common ide devices, the 4-core power plug can also provide power to the fan or video card of the purchased chassis. Switching is often required for connection, you only need to insert the public header at the output end into the master header at the connection end.
CPU fan connection: After a radiator is installed for the

1. Basic judgment on hardware damage
First, listen carefully to hardware such as the hard disk and power supply fan for abnormal sound
that the biggest difficulty in R D of router cluster products lies in the Information Synchronization and collaboration between multiple devices to achieve data exchange plane and system control plane. "In addition to integrating the functions of all single devices, the Cluster also needs to handle the changes brought about by multiple chassis, which is much more complicated than the design of a single device ." Jin Xin said.
It is worth noting that
No fault is displayed at startup. (No alarm sound)
Step 2: First, check whether the external wiring of the computer is connected, and re-insert the connections to check whether the fault is rectified.
Step 2: If the fault persists, open the trunk box to check whether there is any excess metal in the chassis, or short circuit caused by deformation of the motherboard. Then, smell whether the chassis is bu

The chassis anti-theft Monitor can detect if the chassis is open. The "chassis intrusion" (chassis anti-theft) option in the System Setup program displays the status of the
At present, there are a lot of users, when the mic is connected before the connection can not be successful. Here is a detailed description of the wiring method of the front microphone for your reference.

', js_unescape ($ _ REQUEST ['p _ sort ']);
At this point, we have successfully reversed the js escape code.
As follows:
In addition, I found a function that uses PHP to implement js escape encoding:
The code is as follows:
Function phpescape ($ str)
{
$ Sublen = strlen ($ str );
$ RetrunString = "";
For ($ I = 0; $ I {
If (ord ($ str [$ I]) >= 127)
{
$ TmpString = bin2hex (iconv ("gb2312", "UCS-2", substr ($ str, $ I, 2 )));
// $ TmpString = substr
FE.Unicode character SetFunction: Unified coding for 650 languages of the world, compatible with iso-8859-1.Number of digits: The Unicode character set is encoded in multiple ways, utf-8,utf-16 and UTF-32, respectively.BIG5 Character SetFunction: Unify traditional Chinese characters encoding.Number of digits: represented by 2 bytes, representing 13,053 kanji.Range: High byte from A1 to F9, low byte from 40 to 7E,A1 to FE.GB18030 Character SetFunction: It solves the encoding of Chinese, Japanese
UTF Encoding the UTF-8 is 8-bit to encode the UCS. The encoding method from UCS-2 to UTF-8 is as follows:
UCS-2 coding (hexadecimal)

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-2. The UCS (U
MBCS. Also, in the default locale of the simplified Chinese windows, refer to GBK. 1.3. UnicodeLater, someone began to think that too much coding caused the world to become too complex, so that the brain hurts, so we sit together and shoot the head to come up with a method: All language characters are expressed in the same character set, which is Unicode.The original Unicode standard UCS-2 uses two bytes to represent one character, so you can often h

assign page numbers, GBK is the No. 936 page, that is, CP936. Therefore, you can also use CP936 to represent GBK.
MBCS (Multi-Byte Character Set) is a generic term for these encodings. So far everyone has used double-byte, so it is sometimes called DBCS (Double-byte Character Set). It's important to be clear that MBCS is not a particular encoding, and in Windows, depending on the area you set up, MBCS refers to different encodings, and Linux cannot use MBCS as the encoding. You can't see MBCS
