Can I ask for the unicode supported feature.
The next version will be able to read and write UTF-8 files, but that's not enough. I still have to find a solution for fig2dev, because it's not enough that WinFIG supports UTF-8. It also must be able to export LaTeX/PS and al the other formats using UTF-8 encoding, which is possible but a lot of work. But what happens after exporting to PostScript? Not much, because PostScript does not easily support UTF-8. You will need PostScript fonts with glyphs for unicode characters. I don't have any.
You could create one following
these instructions.
But it would be better to have versions of the PS fonts with unicode glyphs. Without that, unicode support will not really bring a benefit.
