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

escape encoding function: Copy Code code as follows: function Phpescape ($STR) { $sublen =strlen ($STR); $retrunString = ""; for ($i =0; $i { if (Ord ($str [$i]) gt;=127) { $tmpString =bin2hex (iconv ("gb2312", "Ucs-2", substr ($str, $i, 2)); //$tmpString =substr ($tmpString, 2,2). substr ($tmpString, 0,2); You may want to open this item under window $retrunString. = "%u". $tmpString; $i + +; } else { $retrunString. = "%"

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

', 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) the UTF-8 byte stream (Binary) 0000-007f 0 xxxxxxx 0080-07ff 110 XXXXX 10 xxxxxx 0800-FFF

addition, I found a PHP implementation of the Escape encoding function: Copy CodeThe 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))); $tmpString =substr ($tmpString, 2,2). substr ($tmpString, 0,2); window may open this $retrunString. = "%u". $tmpString; $i + +; } else { $retrunString. = "%".

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
