PyUnicode_FromString() uses the UTF-8 decoder. I don't think that curses uses any non-ASCII name for a key. If we get a name which is not decodable from UTF-8, I bet that we have a more serious issue than the encoding. I prefer not to change the encoding for getkey (UTF-8 is just fine).

It looks like nobody saw this issue since months, even after the final release of Python 3.3. I'm closing this issue. It doesn't contain any useful information, it would be easy to reopen it or open a new issue.
