As I have tried, I really don't see any of the mentioned problems when
using my plan9 machine directly; I only see the problems in the p9p
and heirloom troff.

Further, when I take the directory /sys/lib/postscript/font from plan9
and copy it to (replace with it) the contents of p9p's
$PLAN9/postscript/font I get a result quite similar to the previously
shown output of the heirloom suite, i.e., everything is present,
however the square-root sign is wrongly placed.

If you know any reason why the square-root symbol is ok on p9 and
wrong on p9p (or also how to get it right), please tell...

Thank you,
Ruda

PS.: The story shows that even when using Times Roman, some (quite
usual) letters (like em-dash, dagger,...) are taken from Lucida Sans.
This isn't particularly nice.
