I am not sure what you are driving at here, since I started with an
ascii file, whereas you just write a unicode file to start with. I
guess the direct question is "is there a simple way to convert my
ascii file to a utf16 file?". I thought either string.encode() or
writing to a utf16 file would do the trick but it probably isn't that
simple!
I used a binary file editor I have used a great deal for all sorts of
things to get the hex values.
