Thank you Bill,
That does enable the μ to display correctly. I guess I will have to
learn which fonts know unicode. The MSung-Light does, however, result
in a strange spacing of the letters in the word "Wavelength" in the
xcaption. I will have to experiment with fonts.
Devon also indicated that was my problem.

I can reproduce the behavior.
require'plot'
pd */~ i: 10
pd 'ycaption Polarization (-Q/I) for μ = 0.1'
pd 'show pdf'
The problem is pdf output default using Helvetica which
is not unicode enabled. It you specify a CID font such as
pd 'captionfont MSung-Light 15'
Then plot will encode the text as 16-bit ucs unicode which is
the encoding expected by acrobat and output is ok.

I generated a pdf file of the plot using j807 in Ubuntu and find it also
produces a plot with the 1/4 character -- and again pd 'show' displays the
figure with μ correctly. At this point, I haven't a clue ...
