Thanks Michael, for these macros, but I have some problem: the one you
sent yesterday doesn't work properly: I get a mixing of a w with an n
with a trema above....?????

The \dotontop you sent today works.

Ross system also works, but the difference is that with Ross'
construction, italics are not working and I don't know why.

Italics are working with your macros but with a strange behaviour: there
is a big space added before the letter with dot (over or under).

I try to undertand the thread from 2005 archives but it is quite
complicated for me....

Thanks for helping.

Best regards

François
