i gather that an overline is not possible with the postscript
terminal.

e.g. in LaTeX, $\overline{x}$ gives you "xbar". ps_guide.ps doesn't
have this listed.

The postscript terminal per se is not a problem.
PostScript itself, on the other hand....

Anyhow

The Unicode character COMBINING MACRON at code point 0304 
or perhaps CONBINING OVERSCORE at code point 0305 should do
what you want.  There are instructions in the .../term/PostScript
subdirectly describing one way of persuading PostScript to accept
unicode characters.  So in case of desparation that would be one
way to go.  But it's painful.

It would be easier to use the pdfcairo terminal, which understands
UTF-8 natively, and then convert the output to PostScript if that
is really necessary.  The pdf2ps conversion program knows how to
dummy up a termporary encoding for single characters so that
PostScript can print them.
