实现UTF8转换GB2312国标码的asp代码

复制代码 代码如下:

'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
