string utfinfo = "document.write(/"alert('aa你好么？？');/");";
string gb2312info = string.Empty;

Encoding utf8 = Encoding.UTF8;
Encoding gb2312 = Encoding.GetEncoding("gb2312");

// Convert the string into a byte[].
byte[] unicodeBytes = utf8.GetBytes(utfinfo);
// Perform the conversion from one encoding to the other.
byte[] asciiBytes = Encoding.Convert(utf8, gb2312, unicodeBytes);

// Convert the new byte[] into a char[] and then into a string.
// This is a slightly different approach to converting to illustrate
// the use of GetCharCount/GetChars.
char[] asciiChars = new char[gb2312.GetCharCount(asciiBytes, 0, asciiBytes.Length)];
gb2312.GetChars(asciiBytes, 0, asciiBytes.Length, asciiChars, 0);
gb2312info = new string(asciiChars);

汉字转换为UTF-8

function chinese2unicode(Str)
dim i
dim Str_one
dim Str_unicode
for i=1 to len(Str)
Str_one=Mid(Str,i,1)
Str_unicode=Str_unicode&chr(38)
Str_unicode=Str_unicode&chr(35)
Str_unicode=Str_unicode&chr(120)
Str_unicode=Str_unicode& Hex(ascw(Str_one))
Str_unicode=Str_unicode&chr(59)
next
Response.Write Str_unicode
end function

UTF-8 To GB2312

function UTF2GB(UTFStr)
for Dig=1 to len(UTFStr)
if mid(UTFStr,Dig,1)="%" then
if len(UTFStr) >= Dig+8 then
GBStr=GBStr & ConvChinese(mid(UTFStr,Dig,9))
Dig=Dig+8
else
GBStr=GBStr & mid(UTFStr,Dig,1)
end if
else
GBStr=GBStr & mid(UTFStr,Dig,1)
end if
next
UTF2GB=GBStr
end function

function ConvChinese(x)
A=split(mid(x,2),"%")
i=0
j=0
for i
