You'll be pleased that this 'text' translation feature will be built in to
win32lib soon. I have the outline of it working now but there is still a few
'issues' to sort out. So maybe it'll appear in a few weeks, after the next
release.

I first ran into this technique many many years ago using an IBM mainframe
programming language called 'UFO' - User-Files-Online.
