Export sheet as UTF-8 CSV file (using Excel-VBA) - utf-8

Question

I would like to export a file I have created in UTF-8 CSV using VBA. From searching message boards, I have found the following code that converts a file to UTF-8 (from this thread):
Sub SaveAsUTF8()
Dim fsT, tFileToOpen, tFileToSave As String
tFileToOpen = InputBox("Enter the name and location of the file to convert" & vbCrLf & "With full path and filename ie. C:\MyFolder\ConvertMe.Txt")
tFileToSave = InputBox("Enter the name and location of the file to save" & vbCrLf & "With full path and filename ie. C:\MyFolder\SavedAsUTF8.Txt")
tFileToOpenPath = tFileToOpen
tFileToSavePath = tFileToSave
Set fsT = CreateObject("ADODB.Stream"): 'Create Stream object
fsT.Type = 2: 'Specify stream type – we want To save text/string data.
fsT.Charset = "utf-8": 'Specify charset For the source text data.
fsT.Open: 'Open the stream
fsT.LoadFromFile tFileToOpenPath: 'And write the file to the object stream
fsT.SaveToFile tFileToSavePath, 2: 'Save the data to the named path
End Sub
However, this code only converts a non-UTF-8 file to UTF-8. If I were to save my file in non-UTF-8 and then convert it to UTF-8, it would have already lost all the special characters it contained, thus rendering the process pointless!
What I'm looking to do is save an open file in UTF-8 (CSV). Is there any way of doing this with VBA?
n.b. I have also asked this question on the 'ozgrid' forum. Will close both threads together if I find a solution.

Finally in Office 2016, you can simply savs as CSV in UTF8.
Sub SaveWorkSheetAsCSV()
Dim wbNew As Excel.Workbook
Dim wsSource As Excel.Worksheet, wsTemp As Excel.Worksheet
Dim name As String
Set wsSource = ThisWorkbook.Worksheets(1)
name = "test"
Application.DisplayAlerts = False 'will overwrite existing files without asking
Set wsTemp = ThisWorkbook.Worksheets(1)
Set wbNew = ActiveWorkbook
Set wsTemp = wbNew.Worksheets(1)
wbNew.SaveAs name & ".csv", xlCSVUTF8 'new way
wbNew.Close
Application.DisplayAlerts = True
End Sub
This will save the worksheet 1 into csv named test.

Update of this code. I used this one to change all .csv files in a specified folder (labeled "Bron") and save them as csv utf-8 in another folder (labeled "doel")
Sub SaveAsUTF8()
Dim fsT As Variant, tFileToOpen As String, tFileToSave As String
Dim Message As String
Dim wb As Workbook
Dim fileName As String
Set wb = ActiveWorkbook
With Application
.ScreenUpdating = False
.DisplayAlerts = False
End With
Message = "Source folder incorrect"
SourceFolder = wb.Worksheets("Menu").Range("Bron") & "\"
If Dir(SourceFolder, vbDirectory) = "" Or IsEmpty(SourceFolder) Then GoTo errorhandler
Message = "Target folder incorrect"
TargetFolder = wb.Worksheets("Menu").Range("Doel") & "\"
If Dir(TargetFolder, vbDirectory) = "" Or IsEmpty(TargetFolder) Then GoTo errorhandler
fileName = Dir(SourceFolder & "\*.csv", vbNormal)
Message = "No files available."
If Len(fileName) = 0 Then GoTo errorhandler
Do Until fileName = ""
tFileToOpen = SourceFolder & fileName
tFileToSave = TargetFolder & fileName
tFileToOpenPath = tFileToOpen
tFileToSavePath = tFileToSave
Set fsT = CreateObject("ADODB.Stream"): 'Create Stream object
fsT.Type = 2: 'Specify stream type – we want To save text/string data.
fsT.Charset = "utf-8": 'Specify charset For the source text data.
fsT.Open: 'Open the stream
fsT.LoadFromFile tFileToOpenPath: 'And write the file to the object stream
fsT.SaveToFile tFileToSavePath, 2: 'Save the data to the named path
fileName = Dir()
Loop
Message = "Okay to remove all old files?"
If QuestionMessage(Message) = False Then
GoTo the_end
Else
On Error Resume Next
Kill SourceFolder & "*.csv"
On Error GoTo errorhandler
End If
the_end:
With Application
.ScreenUpdating = True
.DisplayAlerts = True
End With
Exit Sub
errorhandler:
With Application
.ScreenUpdating = True
.DisplayAlerts = True
End With
CriticalMessage (Message)
Exit Sub
End Sub
'----------
Function CriticalMessage(Message As String)
MsgBox Message
End Function
'----------
Function QuestionMessage(Message As String)
If MsgBox(Message, vbQuestion + vbYesNo) = vbNo Then
QuestionMessage = False
Else
QuestionMessage = True
End If
End Function

Here's my solution based on Excel VBA - export to UTF-8, which user3357963 linked to earlier. It includes macros for exporting a range and a selection.
Option Explicit
Const strDelimiter = """"
Const strDelimiterEscaped = strDelimiter & strDelimiter
Const strSeparator = ","
Const strRowEnd = vbCrLf
Const strCharset = "utf-8"
Function CsvFormatString(strRaw As String) As String
Dim boolNeedsDelimiting As Boolean
boolNeedsDelimiting = InStr(1, strRaw, strDelimiter) > 0 _
Or InStr(1, strRaw, Chr(10)) > 0 _
Or InStr(1, strRaw, strSeparator) > 0
CsvFormatString = strRaw
If boolNeedsDelimiting Then
CsvFormatString = strDelimiter & _
Replace(strRaw, strDelimiter, strDelimiterEscaped) & _
strDelimiter
End If
End Function
Function CsvFormatRow(rngRow As Range) As String
Dim arrCsvRow() As String
ReDim arrCsvRow(rngRow.Cells.Count - 1)
Dim rngCell As Range
Dim lngIndex As Long
lngIndex = 0
For Each rngCell In rngRow.Cells
arrCsvRow(lngIndex) = CsvFormatString(rngCell.Text)
lngIndex = lngIndex + 1
Next rngCell
CsvFormatRow = Join(arrCsvRow, ",") & strRowEnd
End Function
Sub CsvExportRange( _
rngRange As Range, _
Optional strFileName As Variant _
)
Dim rngRow As Range
Dim objStream As Object
If IsMissing(strFileName) Or IsEmpty(strFileName) Then
strFileName = Application.GetSaveAsFilename( _
InitialFileName:=ActiveWorkbook.Path & "\" & rngRange.Worksheet.Name & ".csv", _
FileFilter:="CSV (*.csv), *.csv", _
Title:="Export CSV")
End If
Set objStream = CreateObject("ADODB.Stream")
objStream.Type = 2
objStream.Charset = strCharset
objStream.Open
For Each rngRow In rngRange.Rows
objStream.WriteText CsvFormatRow(rngRow)
Next rngRow
objStream.SaveToFile strFileName, 2
objStream.Close
End Sub
Sub CsvExportSelection()
CsvExportRange ActiveWindow.Selection
End Sub
Sub CsvExportSheet(varSheetIndex As Variant)
Dim wksSheet As Worksheet
Set wksSheet = Sheets(varSheetIndex)
CsvExportRange wksSheet.UsedRange
End Sub
