Please read the posting guide and supply the information asked for and the
minimal reproducible example asked for.
I suspect the issue is how you selected 'alpha', but another issue is if
you mean the mathematical symbol alpha or the Greek letter alpha, for the
solution is different in the two cases.

Hello all,
I suspect my problem is not new: I am having difficulty getting an alpha
character to print in a PostScript file made by R graphics (in my legend).
At first, I figured out how to actually get the character on the screen;
however, when I saved the graphic to a PostScript file the alpha character
was replaced by "..".
Obviously, something is not working when encoding. I've tried to change the
encoding using ps.options; however, no matter what I try R encodes the file
using ISOLatin1Encoding. I'm not even certain that changing the encoding
type would solve my problem. I really do not want to resort to using
another file format, as the resulting images are inferior. Is there
something I'm missing here?
Rather a lot ... see the above.
My current solution to the problem: editing the PostScript by hand. I am no
PostScript wizard, so it is not particularly pretty. Here is what the code
originally looks like:
/ps 12 def /Font1 findfont 12 s
0 setgray
167.68 434.79 (..=0.05) 0 0 0 t
167.68 420.39 (..=0.005) 0 0 0 t
167.68 405.99 (..=0.0005) 0 0 0 t
and here is what I've changed it to:
/ps 12 def /Font1 findfont 12 s
0 setgray
167.64 317.78 (Lower Limit, = 0.05) 0 0 0 t
167.64 303.38 (Upper Limit, = 0.05) 0 0 0 t
/Symbol 12 selectfont 240 303.38 moveto
/alpha glyphshow
240 317.78 moveto
/alpha glyphshow
The problem with this solution is that it is a terrible hack. Can someone
please help me find a better solution to this problem?
Thanks,
Scott
