Gordon Peterson made a good point about a difficulty in building a Unicode
version of Icon:

This topic has come up before, and this is a point for which some
infrastructure in the Icon implementation would be needed: minimally, we'd
need to support "bit vectors" with more bits than csets' 256 bit limit, and
in order to be practical we'd need to support sparse bit arrays so that most
Unicode-supporting csets would not have to be an 8K object.
I think these additions would not be very difficult to implement, but
someone would have to spend some time to do them. I'm willing to supervise
a student to do it, but we have to wait for a volunteer or else find some
money to pay a student to do the work. :-)
