As far as I can tell, GD::Graph itself doesn't support Unicode; however, it appears that there is some limited support for Unicode in GD---but it's experimental. To quote the author:

"The interaction between Perl, Unicode, and libgd is not clear to me, and you should experiment a bit if you want to use it."

He was referring to the stringFT() method to load and render Truetype fonts. Specifically, the optional "charmap" hashkey. It can have a Unicode value. You can find more info on it in the GD docs under "Character and String Drawing". See:

GD
