Hovertext characters problem

Hi all,

I have got a prim that uses hovertext to display specific characters. I can see the text perfectly okay. When I give the prim to other people, 50% of them say they see blocks instead of the characters.

Is there something specific needed in SL to be setup to show these characters?
Or is this down to some font/unicode setup on individual computers?

Thanks.

I believe you've got it with the font/UNICODE guess. I'm not sure if the viewer is supposed to come with all the necessary fonts, but in reality I'm pretty sure it doesn't (or there's some font or font path configuration issue on some systems at least).
