Sure. However, that requires you to provide meaningful, reproducible counter-examples, rather than a stenographic formulation that might hint some problem you apparently see (which I believe is just not there).

Well, here's another one: PEP 383 would disallow UTF-8 encodings of half surrogates. But such encodings are currently supported by Python, and they are used as part of CESU-8 coding. That's, in fact, a common way of converting UTF-16 to UTF-8. How are you going to deal with existing code that relies on being able to code half surrogates as UTF-8?

Can you please elaborate? What code specifically are you talking about?

Regards, Martin
