Text files in Windows don't have a format. There's an unofficial convention that if the file starts with the <a href="http://en.wikipedia.org/wiki/Byte_order_mark#UTF-8" rel="nofollow noreferrer">BOM codepoint in UTF-8 format</a> that it's UTF-8, but that convention isn't universally supported. That would be the 3 byte sequence <code>"\xef\xbf\xbe"</code>, i.e. <code>ï¿¾</code> in the Latin-1 character set.

I had a directory of files that I wanted to check. I created an Excel macro to determine ANSI vs. UTF-8. This worked for me.

<pre><code> Sub GetTextFileEncoding()
 Dim sFile As String
 Dim sPath As String
 Dim sTextLine As String
 Dim iRow As Integer

 'Set Defaults and Initial Values
 iRow = 1
 sPath = "C:textfiles\"
 sFile = Dir(sPath &amp; "*.txt")

 Do While Len(sFile) &gt; 0
 'Get FileType
 'Debug.Print sFile &amp; " - " &amp; FileEncodeType(sPath &amp; sFile)

 'Show on Excel Worksheet
 Cells(iRow, 1).Value = sFile
 Cells(iRow, 2).Value = FileEncodeType(sPath &amp; sFile)

 'Get next file
 sFile = Dir

 'Increment Row
 iRow = iRow + 1
 Loop
 End Sub

 Function FileEncodeType(sFile As String) As String
 Dim bEF As Boolean
 Dim bBB As Boolean
 Dim bBF As Boolean

 bEF = False
 bBB = False
 bBF = False

 Open sFile For Input As #1
 If Not EOF(1) Then
 'Read first line
 Line Input #1, textline
 'Debug.Print textline
 For i = 1 To 3
 'Debug.Print Asc(Mid(textline, i, 1)) &amp; " - " &amp; Mid(textline, i, 1)
 Select Case i
 Case 1
 If Asc(Mid(textline, i, 1)) = 239 Then
 bEF = True
 End If
 Case 2
 If Asc(Mid(textline, i, 1)) = 187 Then
 bBB = True
 End If
 Case 3
 If Asc(Mid(textline, i, 1)) = 191 Then

 End If
 Case 4

 End Select

I have converted a .txt file from ASCII to UTF-8 using UltraEdit. However, I am not sure how to verify if it is in UTF-8 format in Windows environment. 

Thank you!

我已经使用UltraEdit将一个.txt文件从ASCII码转换为UTF8。但是，我不确定如何在Windows环境下验证它是否为UTF-8格式。谢谢!
