1、'UTF轉GB---將UTF8編碼文字轉換為GB編碼文字
復制代碼 代碼如下:
function UTF2GB(UTFStr)
for Dig=1 to len(UTFStr)
'如果UTF8編碼文字以%開頭則進行轉換
if mid(UTFStr,Dig,1)="%" then
'UTF8編碼文字大于8則轉換為漢字
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
'UTF8編碼文字將轉換為漢字
function ConvChinese(x)
A=split(mid(x,2),"%")
i=0
j=0
for i=0 to ubound(A)

next

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
'二進制代碼轉換為十六進制代碼
function c2to16(x)
i=1
for i=1 to len(x) step 4
c2to16=c2to16 & hex(c2to10(mid(x,i,4)))
next
end function
'二進制代碼轉換為十進制代碼
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
'十六進制代碼轉換為二進制代碼
function c16to2(x)

else

end if
next
if mysign=-1 then c10to2="-" & c10to2
end function
2、'GB轉UTF8--將GB編碼文字轉換為UTF8編碼文字
復制代碼 代碼如下:
Function toUTF8(szInput)
Dim wch, uch, szRet
Dim x
Dim nAsc, nAsc2, nAsc3
'如果輸入參數為空，則退出函數
If szInput = "" Then
toUTF8 = szInput
Exit Function
End If
'開始轉換
For x = 1 To Len(szInput)
'利用mid函數分拆GB編碼文字
wch = Mid(szInput, x, 1)
'利用ascW函數返回每一個GB編碼文字的Unicode字符代碼
'注：asc函數返回的是ANSI 字符代碼，注意區別
nAsc = AscW(wch)
If nAsc < 0 Then nAsc = nAsc + 65536
If (nAsc And &HFF80) = 0 Then
szRet = szRet & wch
Else
If (nAsc And &HF000) = 0 Then
