One day I had a chance to play around with the Arabic
version of MS Word. As the first letter is entered, the
isolated form appears. Then the next letter is typed, and
appears in the final form, while the first letter changes
to the initial form. Then the third letter is entered, and
it appears in the final form, while the second letter
changes to the medial form.

I realize that this is not the same as would happen in
Korean, but I didn't find this changing of characters
to be a problem.
