Herbert. I like it! One problem is that if I compiile with pdflatex to
get a pdf or with latex to get a dvi file, the results differ. In the
dvi file the N breaks through the top of the circle a little. In the
pdf the N is a bit high, but not so much as to near hi\igging the
cirfle. When I put the code into a document I happen to be currently
writing, the N is a bit too low. How is the mu unit measured for /mkern?
Is it a function of the current font? If so I'll have to specify a
monospace font
