Marc, perhaps Unicode has refined their definitions since you last looked? Valid UTF-8 cannot contain surrogates[1]. If it does, you have CESU-8[2][3], not UTF-8. So there are two bugs: first, the UTF-8 codec should refuse to load surrogates. Second, since the original bug showed up before the .pyc is created, something in the parse/compilation/whatever stage is producing CESU-8.

Marc, perhaps Unicode has refined their definitions since you last looked?

Valid UTF-8 *cannot* contain surrogates[1].  If it does, you have
CESU-8[2][3], not UTF-8.

So there are two bugs: first, the UTF-8 codec should refuse to load
surrogates.  Second, since the original bug showed up before the .pyc is
created, something in the parse/compilation/whatever stage is producing
CESU-8.
