Is it valid though? Standard library rules are ascii only (as referenced by Guido in this thread). If you need the characters in a string literal you must escape them.
Nope - those are the "few specific encoding test cases" he mentioned in that email. They take advantage of the utf-8 encoding of the source files these days.
One would have thought that "test cases" referred to test cases, not strings in non-test code, and that the "the stdlib is already supposed to be ASCII only" meant that the standard library is supposed to be ASCII only, not UTF-8.
