A multilingual Unicode font (TTF, TrueType font) for ancient languages: classic & medieval Latin, ancient Greek, Old Italic - Etruscan, Oscan, Umbrian, Faliscan, Messapic, Picene - Gothic, Iberian, Celtiberian, old & middle English, Hebrew, Sanskrit, Runic, Ogham, Ugaritic, Old Persian cuneiform, Phoenician, old & medieval Nordic and linguistics (I.P.A.)
But do I want just the font at £15 (the £10 licence is just too restrictive: no PDF embedding; no use in publication), or the font and all the nice toys on CD at £45? I'll have to think about it. But the author's obviously put a huge amount of work into it, and he ought to get some pennies for all of that, even if I don't need all the wonderfulness.
Then again, I don't need a font, do I?
But, oh! — fonty goodness!
 Yes, you may consider this to be a plug, if you like. Given the quality and the work that's gone into it, and the price, it's a sodding bargain. Go and buy it, and tell him I sent you — I might get a discount if enough of you do :D
