### postscript terminal : no overline

• Email

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.

Wasn't enhanced text mode invented to make things like this possible?

It's right there among the examples of 'help enhanced':

set term post enh
set out "test.ps"
set label 1 "~x{.8-}"  # <---- there
set out

Font size postscript terminal Hello all, I set up a postscript terminal with options eps enhanced and using the fontfile for european modern roman optimized for 10pt as suggested in the documentation. The problem now is, that using the postscript file in latex with includegraphics and no scaling the font is very small in comparison to the 10 pt latex font. To get approximately the same size I have to scale the font in gnuplot to 22 ("FSRM1000" 22). Is this normal? Where the differences in size come from?
