[R] Registered / trademark signs

[Dennis Fisher]

Colleagues,

What is the easiest means to embed a:
	® (registered)
or
	™ (trademark)
sign in text in a graphic.  I would like to use mtext and avoid plotmath, if possible.  Ideally, the sign should be superscripted but I can easily sacrifice that.

Optimally, I need a solution that works in both OS X and Windows (≥ XP) and with R versions ≥ 2.11

Thanks in advance.

Dennis
