I'm thinking about an approach of a variable representation: one, two, or four bytes, depending on the widest character that appears in the string. I think it can be arranged to make this mostly backwards-compatible with existing APIs, so it doesn't need to wait for py4k, IMO.

Given that this is vaporware: proceed as if that idea didn't exist.

I'm thinking about an approach of a variable representation:
one, two, or four bytes, depending on the widest character that
appears in the string. I think it can be arranged to make this mostly
backwards-compatible with existing APIs, so it doesn't need to wait
for py4k, IMO. OTOH, I'm not sure I'll make it for 3.3.

Given that this is vaporware: proceed as if that idea didn't exist.
