Many thanks for this. I have just run into trouble with endashes in
Gill Sans. (r hyphen) is kerned, and looks neat. TeX therefore gives
(r endash) has the same kern, which makes the endash nearly collide
with the r, as endash is further from the baseline than hyphen...

Is there any way around this except a future e-TeX?

Thanks
