Marc's proposed solution (appearing at the end of this email) is perfect -- thanks so much
However, some questions remain:

1.  The following works:
	plot(1, type="n")
	text(1, 1, expression(symbol("\342")))

but this does not work (TEXT appears in a symbol font)
	plot(1, type="n")
	TEXT	<- "\342"
	text(1, 1, expression(symbol(TEXT)))

nor does this work (it yields:	Error: could not find function "symbol")
	plot(1, type="n")
	TEXT	<- symbol("\342")
	text(1, 1, expression(TEXT))
Clearly, I do not understand the subtleties of plotmath.  Could someone explain?

2.  How would one learn that \342 corresponds to the copyright sign in the symbol font? (i.e., is there a list of all possible characters)
