arthur told me that can arise rounding errors.
You have to remember I used to be a mathematician. I say things that are meant to be true, not meant to be helpful :-)
If you want to be sure that LuaTeX's output looks right in the most recent versions of Adobe Reader, editing the font is the way to go (although there might be license issues with commercial fonts). Of course conversion is not perfect, but you can't have it both way! Besides, the metrics won't change if you only modify upm; only the outlines do.
I should try to convert to Type1 instead
That should indeed work if you don't need more than 256 glyphs in the font (are you *sure* you don't?).

what I mean is: chose an encoding convert otf to type1 as is, make a pdf with mkiv check if it's ok. It's only for experiment , of course: Fell type come with a native ttf edition which is OK (or better, really OK), and one should chose this one to avoid any problems (so eventually I can compare pdfs ). -- luigi
