Greek letters in the EMF terminal

[James R. V. Z. <jr...@co...>]

Ordinarily I use the EMF or CGM terminals to generate plots for
PowerPoint charts.  However now I have a series of charts where the
labels should include Greek letters, and the EMF terminal's support
for "enhanced text" appears to be broken.  Any labels that use
"enhanced" features (superscripts and/or Symbol font) do not appear at
all.

For example, with this version of gnuplot under Linux:

        G N U P L O T
        Version 4.3 patchlevel 0
        last modified March 2009

and these commands:

   set term emf enhanced
   set label "vanilla label"                          at graph .1,.9
   set label "H_2SO_4"                                at graph .1,.7
   set label "{/Symbol s} is the Greek letter sigma"  at graph .1,.5
   set label "e^{i{/Symbol p}}=-1"                    at graph .1,.3
   set label "abcde"                    font "Symbol" at graph .1,.1
   set out "sine.emf"; plot sin(x); set out

only the first and last labels appear.  The Symbol font is available,
since the last label is displayed with Greek letters.

I also tried this version of gnuplot on Windows XP, with the same result:

        G N U P L O T
        Version 4.3 patchlevel 0
        last modified November 2008
        System: MS-Windows 32 bit

Any suggestions for getting the EMF terminal to work?

p.s. I'll probably wind up adding "enhanced text" support to the CGM
terminal.
