VB6如何实现UTF-8 unicode的混合编码转换

如何将如下这段代码转换成完整的可以正常阅读的代码？

\"module=stissue\"\n\tnode-type=\"publishBtn\" title=\"\u53d1\u5e03\u5fae\u535a\u6309\u94ae\">ru'he

重新改过，在xp已经过测试可用
Option Explicit
Private Declare Function MultiByteToWideChar Lib "kernel32" (ByVal CodePage As Long, ByVal dwFlags As Long, ByRef lpMultiByteStr As Any, ByVal cchMultiByte As Long, ByVal lpWideCharStr As Long, ByVal cchWideChar As Long) As Long
Private Const CP_UTF8 = 65001
'Purpose:Convert Utf8 to Unicode
Public Function UTF8_Decode(ByVal sUTF8 As String) As String
Dim lngUtf8Size As Long
Dim strBuffer As String
Dim lngBufferSize As Long
Dim lngResult As Long
Dim bytUtf8() As Byte
Dim n As Long
If LenB(sUTF8) = 0 Then Exit Function
On Error GoTo EndFunction
bytUtf8 = StrConv(sUTF8, vbFromUnicode)
lngUtf8Size = UBound(bytUtf8) + 1
On Error GoTo 0
'Set buffer for longest possible string i.e. each byte is
'ANSI, thus 1 unicode(2 bytes)for every utf-8 character.
lngBufferSize = lngUtf8Size * 2
strBuffer = String$(lngBufferSize, vbNullChar)
'Translate using code page 65001(UTF-8)
lngResult = MultiByteToWideChar(CP_UTF8, 0, bytUtf8(0), _
lngUtf8Size, StrPtr(strBuffer), lngBufferSize)
'Trim result to actual length
If lngResult Then
UTF8_Decode = Left$(strBuffer, lngResult)
End If
EndFunction:
End Function

Private Sub Command1_Click()
Dim str_UTF8 As String
Dim str_Unicode As String
Open "c:\UTF8.txt" For Binary As 1
Seek #1, 1
str_UTF8 = StrConv(InputB$(LOF(1), 1), vbUnicode) '读到字符串
str_UTF8 = Right(str_UTF8, Len(str_UTF8) - 1) '第一个字符是格式标志，无实际意义，去掉
Close 1
str_Unicode = UTF8_Decode(str_UTF8) '转换为Unicode
Text1.Text = str_Unicode '显示到文本框
'保存到Unicode格式文件
Open "c:\ANSI.txt" For Binary As #1
Put #1, , str_Unicode
Close #1
End Sub

你去搜一下“有暗号”就知道了

本人百度知道14级回答，呵呵！采纳把！

追问

不行喔。。。。。，你用我那段字符串测试过了？

这段字符串是正常的英文和\u53d这种中文混合，就是要将\u53d这种转换成中文，其他不转换。
