Unicode and Chinese character encoding knowledge
Unicode encoding of Chinese characters, such as "King", which becomes "\ u738b". The Unicode character starts with "\ U" and is followed by four numbers or letters, all characters are hexadecimal numbers. Each two character represents a number less than 256. A Chinese character is composed of two characters, so it is easy to understand that "738b" is two characters, namely "73" and "8b ". However, when converting the Unicode character encoding content into Chinese characters,The characters are processed forward from the back., So,You need to combine characters in the order of "8b" and "73" to obtain Chinese characters..



The following code converts the Unicode codes of C # Chinese characters.


-C #

Public Class Gb2312unicodeconverter

Public Static String Tounicode ( String Str) 
{ 
Byte [] BTS = encoding. Unicode. getbytes (STR ); 
String R = "" ; 
For ( Int I = 0; I <BTS. length; I + = 2) R + = "\ U" + BTS [I + 1]. tostring ( "X" ). Padleft (2, '0') + BTS [I]. tostring ( "X" ). Padleft (2, '0 '); 
Return R; 
}

{ 
String R = "" ; 
Matchcollection MC = RegEx. Matches (STR ,@ "\ U ([\ W] {2}) ([\ W] {2 })" , Regexoptions. Compiled | regexoptions. ignorecase ); 
Byte [] BTS = New Byte [2]; 
Foreach (Match m In MC) 
{ 
BTS [0] = ( Byte ) Int . Parse (M. Groups [2]. Value, numberstyles. hexnumber ); 
BTS [1] = ( Byte ) Int . Parse (M. Groups [1]. Value, numberstyles. hexnumber ); 
R + = encoding. Unicode. getstring (BTS ); 
} 
Return R; 
} 
}


Tip: It seems that Unicode to Chinese Characters in. Net 4.0 has been directly completed by the compiler --!
