I blocked the fix in Python 3.1 because it's non trivial and I prefer to avoid complex changes in Python 3.1. But then I realized that Python 3.1 has two bugs about environment variables. It uses sys.getfilesystemencoding()+surrogateecape to decode variables and sys.getdefaultencoding()+strict to encode variables: the encoding is different! It counts the number of characters to allocate the byte string buffer and so non-ASCII values are truncated. So I decided to backport the fix: r80494.

It counts the number of *characters* to allocate the *byte* string buffer and so non-ASCII values are truncated.
