Well, you can't please everybody: ticket #493 complains because Unicode isn't mandatory, this one because it isn't omitted altogether. I proposed UnicodeCowan, which is substantially what WG1 adopted, on the following principles:

  1. No small Scheme implementation is required to support any specific Unicode character or repertoire (collection of characters), with the obvious exception of the ASCII repertoire.
  1. Unicode is the predominant character standard today, and a small Scheme implementation's treatment of characters must conform to it, insofar as this does not conflict with Principle 1.

I think that's the best that a small language that is also a modern language can do. Again, see ​my ballot for a discussion of the difference between the "best possible result" and "the best result possible".


The WG decided by unanimous consent to take no action on this ticket.
