Sorry for the noise. I did not read to the end and then pasted the
wrong code in as well.

I intended to post a suggestion to use:

text(1,1, expression(mu))

I'm guessing it is happening because different fonts or families are
being used for quartz and pdf devices. But I am not skilled at
managing fonts.
