Eliot -- I'm having a problem tracking down any of the images I had when I was playing with this last year. However, some of my issue was documented in this mailing list exchange. Note that in my examples I'm using the Assurbanipal ttf font available here. My recollection is that the cuneiform (and perhaps other ancient script) fonts use unicode points that are higher than what Squeak's font handling is able to deal with. For example, all of the cuneiform stuff is from U+12000 to U+1254F.
