CONVERT ASCII TO UTF WITH MACRO

I would like to know the method that can be used, in a macro that will
convert a text file that is in ASCII to UTF-8. The current method that is
used is to open the text document in NotePad and save as UTF-8. When the
macro is performed in Word all of the extra characters do not show up. I
made an attempt to record a macro, thru Word, to perform the above but
apparently because NotePad is a separate application the method will not do
what I expect. Is there a field in the source code that I change change?
The macro is as follows:

Sub ecf_new_test()
'
' ecf_new_test Macro
'
'
ChangeFileOpenDirectory "U:\01 Text Files\"
Documents.Open FileName:="U:\01 Text Files\ecf1.txt",
ConfirmConversions:= _
False, ReadOnly:=False, AddToRecentFiles:=False,
PasswordDocument:="", _
PasswordTemplate:="", Revert:=False, WritePasswordDocument:="", _
WritePasswordTemplate:="", Format:=wdOpenFormatAuto,
XMLTransform:="", _
Encoding:=65001
