I didn't think of editing text of combining diacritics ... :(

I noticed the problem while testing my program for ttf font conversion -- I
never really entered such text. I have to check how other OSes handle such
cases -- I cannot imagine how can one select characters with zero width :)

If somebody changes the code to support right-to-left and mixed
directions text, s/he may take care of the combinig diacritics too :)

Thanks,

If the changes in the algorithms for text editing require too much work, may
be it is better to leave them to
