  最好的方法:
先说一下基本的东西:
<%@ codepage=65001%>UTF-8
<%@ codepage=936%>简体中文
<%@ codepage=950%>繁体中文
<%@ codepage=437 %>美国/加拿大英语
<%@ codepage=932 %>日文
<%@ codepage=949 %>韩文
<%@ codepage=866 %>俄文

codepage指定了IIS按什么编码读取传递过来的串串(表单提交,地址栏传递等)。

出乱码的原因也就是网站要整合的时候模块编码不相同引起的。
就像我的博客相同,整合的时候都会出这个问题,因为BLOG是Utf-8的,
近来很多网友都在为这个问题咨询,我尝试了很多种方法。
最方便的方法如下:
不要转换任何模块网页的编码该utf-8的还是utf-8,该Gb22312的还是Gb2312
在Utf-8模块的包文档(如conn.asp,但是要注意conn.asp必须是在第一行调用)最前面加上
<%@LANGUAGE=VBSCRIPT CODEPAGE=65001%>
在GB2312模块的包文档最前面加上
<%@LANGUAGE=VBSCRIPT CODEPAGE=936%>
<%Session.CodePage=936%>
其他编码的类推。
ASP中汉字与UTF-8的互相转换
=============汉字转换为UTF-8==================

function chinese2unicode(Str)
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
chinese2unicode = Str_unicode
end function



=============UTF-8转换为汉字==================

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=0 to ubound(A)
A(i)=c16to2(A(i))
next

for i=0 to ubound(A)-1
DigS=instr(A(i),0)
Unicode=
for j=1 to DigS-1
if j=1 then
A(i)=right(A(i),len(A(i))-DigS)
Unicode=Unicode & A(i)
else
i=i+1
A(i)=right(A(i),len(A(i))-2)
Unicode=Unicode & A(i)
end if
next

if len(c2to16(Unicode))=4 then
ConvChinese=ConvChinese & chrw(int(&H & c2to16(Unicode)))
else
ConvChinese=ConvChinese & chr(int(&H & c2to16(Unicode)))
end if
next
end function

function c2to16(x)
i=1
for i=1 to len(x) step 4
c2to16=c2to16 & hex(c2to10(mid(x,i,4)))
next
end function

function c2to10(x)
c2to10=0
if x=0 then exit function
i=0
for i= 0 to len(x) -1
if mid(x,len(x)-i,1)=1 then c2to10=c2to10+2^(i)
next
end function

function c16to2(x)
i=0
for i=1 to len(trim(x))
tempstr= c10to2(cint(int(&h & mid(x,i,1))))
do while len(tempstr)<4
tempstr=0 & tempstr
loop
c16to2=c16to2 & tempstr
next
end function

function c10to2(x)
mysign=sgn(x)
x=abs(x)
DigS=1
do
if x<2^DigS then
exit do
else
DigS=DigS+1
end if
loop
tempnum=x

i=0
for i=DigS to 1 step-1
if tempnum>=2^(i-1) then
tempnum=tempnum-2^(i-1)
c10to2=c10to2 & 1
else
c10to2=c10to2 & 0
end if
next
if mysign=-1 then c10to2=- & c10to2
end function

GB2312转UTF-8

个人代码风格注释(变量名中第一个小写字母表表示变量类型)
i:为Integer型;
s:为String;
Function U2UTF8(Byval a_iNum)
Dim sResult,sUTF8
Dim iTemp,iHexNum,i

iHexNum = Trim(a_iNum)

If iHexNum = Then
Exit Function
End If

sResult =

If (iHexNum < 128) Then
sResult = sResult & iHexNum
ElseIf (iHexNum < 2048) Then
sResult = ChrB(&H80 + (iHexNum And &H3F))
iHexNum = iHexNum \ &H40
sResult = ChrB(&HC0 + (iHexNum And &H1F)) & sResult
ElseIf (iHexNum < 65536) Then
sResult = ChrB(&H80 + (iHexNum And &H3F))
iHexNum = iHexNum \ &H40
sResult = ChrB(&H80 + (iHexNum And &H3F)) & sResult
iHexNum = iHexNum \ &H40
sResult = ChrB(&HE0 + (iHexNum And &HF)) & sResult
End If

U2UTF8 = sResult
End Function

Function GB2UTF(Byval a_sStr)
Dim sGB,sResult,sTemp
Dim iLen,iUnicode,iTemp,i

sGB = Trim(a_sStr)
iLen = Len(sGB)
For i = 1 To iLen
sTemp = Mid(sGB,i,1)
iTemp = Asc(sTemp)

If (iTemp>127 OR iTemp<0) Then
iUnicode = AscW(sTemp)
If iUnicode<0 Then
iUnicode = iUnicode + 65536
End If
Else
iUnicode = iTemp
End If

sResult = sResult & U2UTF8(iUnicode)
Next

GB2UTF = sResult
End Function
