Oh, I read this incorrectly. Now the Angstrom symbol shows up!
I'm pretty sure mental telepathy is involved. :-)
Cheers,

Just an update:
Since I needed to include a bar scale in the output plots, I included the following line in my code:
oplotscale, -0.5, 1, 0.5, '1175 A.U.',$
color=cgcolor('white'),$
charsize=0.6,$
thick=5, /above
This is an external procedure that I just downloaded from here:
http://www.cita.utoronto.ca/~tchang/gbt/procs/gen/image/oplo tscale.pro
Don't ask me why, but now I can get the Angstrom symbol to be displayed correctly in the output (same PS/PDF viewer).
Best regards!

Did you try printing it on a PostScript printer. I think it will be
fine. :-)
In any case, the code you gave us shows the Angstrom symbol looking
"correct" both in my PostScript and PNG files. Because you mention PDF,
I tried that, too. It looks OK, except that the little circle is
touching the A in the PDF file. You can still tell what it is, though.
Cheers,
David

This is clearly a PostScript viewer program, not a PostScript file
problem. For one thing, the only way for something to show up correctly
in the PNG file is for it to exist (correctly!) in the PostScript file,
since the PNG file is made from the PostScript file.
My guess is that if you turned anti-aliasing off in your PostScript
viewer the Angstrom symbol would show up correctly, as if you were using
the powers of mental telepathy. :-)

David
