GD graph labels: degree symbol?

[parboil]

Hi

I'm using GD::Graph quite successfully, but I'm darned if I can get a
label text string like 'Degrees °C'

I use vi to edit everything, but I've no idea whether I need to
"insert" the o-superscript using a special vi keystroke or whether I
need to do a hex(o-superscript) type bit-o-code inside perl.

Any help gratefully received...

Whatever works. You want a character that displays as a degree
character in the font GD uses to produce label texts. That may
be the same character that works on your screen or not, so forcing
vi to accept the input (type ^V, then the character, in input mode)
may take you only half of the way.
