Dear Ken,

I do not use the isolatin1 keyword because I want to have the per mil
sign, which is gone from the postscript fonts with isolatin1.

So I always use number 176 of the symbol font, which is the degree sign
regardless of isolatin1. Try:
set_plot, 'PS'
stdfont='!4' ; almost whatever you want

xyouts, 0.1, 0.7, font=0, $
stdfont+'Degree Celsius: !9'+string(byte(176))+stdfont+'C'
xyouts, 0.1, 0.4, font=0, $
stdfont+'Per mil: '+string(byte(189))
device, /close

Cheers
Matthias
