Well, the problem is the Angstrom symbol, known as Aring in the PostScript
Reference Manual, is not in the default encoding. According to the manual,
you can provide a font encoding string to put it in a currently "empty"
place such as \201. I'm not a PostScript guru so I can't be sure, but
this might work:

To put this into the IDL PostScript file, you would use
device,output=blah
for each line (I think). But, shouldn't you be using nanometers instead???
I mean, Angstroms aren't strictly SI units.
