我有一个处理utf-8文件的VBscript代码。
它完美地工作。除了源文件存在问题以外，有时输入（尽管脚本已明确标记为用于utf-8文件）是unicode-LE。
这当然会创建损坏的输出。我正在检查BOM，以确保没有正确打开Unicode-LE文件。但是我已经有这种损坏的文件了。
是否有一种无缝恢复损害的方法？是要“不正确地”读回并正确保存它？
代码如下：
Private Sub UnicodeToUTF8(ByVal InFName, ByVal OutFName)
Dim strText
With CreateObject("ADODB.Stream")
.Open
.Type = adTypeBinary
.LoadFromFile InFName
.Type = adTypeText
.Charset = "utf-8"
'Read Unicode source file
strText = .ReadText(adReadAll)
'Process file
strText = OffsetTCs(strText)
'Output UTF-8 file
.Position = 0
.SetEOS
.Charset = "utf-8"
.WriteText strText, adWriteChar
.SaveToFile OutFName, adSaveCreateOverWrite
.Close
End With
End Sub
编辑：
我尝试使用此脚本来保存一天，但是它在file.Write data行上报告了一个错误。它确实在消息框中正确显示了ASCII内容，但没有中文字符：
Dim fso, file, data
Set fso = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("damaged_Test.sub", 1, False, -1)
data = ""
data = file.ReadAll
MsgBox(data)
Set file = fso.OpenTextFile("output.txt", 2, True)
file.Write data
这是损坏文件的十六进制转储：
