Greek letters in the SVG terminal

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

I'm trying to use the svg terminal in a recent version of gnuplot:

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

I can generate a sample file like this:

  set term svg enhanced
  set out "sine.svg"
  set label "e^{i{/Symbol p}}=-1" at graph .5,.5
  plot sin(x)
  set out

When I display the output using inkscape 0.46, I see three problems:

 - All the lines are missing
 - The superscripted characters are spaced out
 - The Greek letter pi appears as "p".

By googling I came up with workarounds for the first two problems:

  perl -p -i -e 's/color:([^;]*); *stroke:[^;]*;/color:$1; stroke:$1;/' sine.svg
  perl -p -i -e 's/xml:space=.preserve.//' sine.svg

Does anyone have suggestions about the Greek letters?
