One thing that was discussed and probably wouldn't take too much time to actually implement (we just never got around to do it) would be to tweak the SVG version to replace the single font with a list of font names that covers fonts with wide character coverage on various platforms. Depending on the font, the spacing may be suboptimal, but it's still better to specify a font that's actually available rather than one that's not. >More info on the issue: >http://www.graphviz.org/doc/FAQ.html#Q10a There seems to be only http://www.graphviz.org/doc/FAQ.html#Q10 and http://www.graphviz.org/doc/FAQ.html#Q10b Regards, Martin. #-#-# Martin J.
