Yes, I agree.

Sounds good. Unfortunately, I'm a bit short of time right now; I'll
think about your algorithm within the next few days. However, please
proceed anyway!

Thanks. Do you have meanwhile found an explanation why o-tilde looks
so bad for Times New Roman at 16ppem?

Will try if I find some time.
