I don't have information one way or another on this. I don't see any bugs that are obviously this issue, but it could be the cause of less obvious compatibility bugs. Perhaps the thing to do is a study to determine the frequency with which non-ASCII cookies are sent.

BTW from code inspection, it looks to me like Safari *will* allow non-ASCII characters in the cookie value if it is a quoted string.
