I'm still studying this.

This definitely will work. I made a test program, and a letter with an accent mark is shown as the same width as a letter without the accent mark. I am playing with this. I'll probably have some more questions later. Many thanks! this is a big breakthrough for me. I have been trying to figure out how to do this for several years, and it is this simple with rebol! Louis
