Please test UTF-8 support in revised SVG driver

[Ethan A M. <merritt@u.washington.edu>]

Hi all,

This weekend I decided to sit down and try to understand how utf-8
encoded works.  Afterwards I modified the svg terminal driver
to re-encode utf-8 strings as escaped Unicode hex constants. This
makes it work properly on my machine using either firefox or
konqueror, whereas without re-encoding it worked only partially.

Please let me know if you find problems viewing the new svg output
in other svg viewers.

Known limitations:
  text centering in svg was not good to begin with, and if the
  text includes utf-8 characters the centering gets even worse.

  You need to select a utf-8 font, of course.  I tested with
	set term svg font "ArialUnicode MS"
