SVG is a subset of XML, for which the standard encoding is UTF-8.
If you enter your characters in UTF-8 you should be OK.
In theory you should also gnuplot "set encoding utf8"
but in practice that doesn't make any difference to the
svg terminal output since it is already the default.

The "usual" font named Symbol is specifically an Adobe font with a
non-standard encoding.  It is useful only for PostScript. 
If you have a non-Adobe font with that name, I don't know what
encoding it uses.

Heh.  That seems to be a bug specific to a background setting
that is identically zero.  Setting the background to '#000001' works.
I will look into it.
