Import Unicode text into excel sheet from Web(html) source

I used this below mentioned code to fetch HTML source from websites. I have no problem fetching data which are in English. But if they are in any other language, i am unable to import that text without turning that text into gibberish.

How can I allow below code to import other language text in their actual form.

Sub test()
Dim FILENAME As String
Dim FileNum As Long

FILENAME = "C:\Temp\Source.txt"
FileNum = FreeFile


Open FILENAME For Output As FileNum
Print #FileNum, GetSource("https://www.pleasehelp.com/thankyou.html")
Close FileNum

    With ActiveSheet.QueryTables.Add(Connection:="TEXT;C:\TEMP\Source.txt", Destination:=Range("A1"))
    .Name = "Source"
    .AdjustColumnWidth = True
    .TextFileParseType = xlFixedWidth
    .TextFileTextQualifier = xlTextQualifierDoubleQuote
    .TextFileColumnDataTypes = Array(2)
    .Refresh BackgroundQuery:=False
End With

End Sub

Function GetSource(sURL As String) As String
Dim oXHTTP As Object
Set oXHTTP = CreateObject("MSXML2.XMLHTTP")
oXHTTP.Open "GET", sURL, False
oXHTTP.send
GetSource = oXHTTP.responsetext
Set oXHTTP = Nothing
End Function
