For all those interested, here is a summary of the "how do I troff an
umlat" question.  My thanks to all those who replied (including some
not mentioned here because I managed to lose some of the mail).  One
reply not included but worth mentioning because it was so simple was
to overstrike an o with a double quote(") char.

Thanks to all, I'm going to use the string defined below since I've
got a really primative version of troff.
