Maybe.  I notice that if you interpret the first byte as a Unicode
code point (as opposed to the first byte of a UTF-8 encoded
character), it is an uppercase letter.  But I can't quite see how
that gets to the decimal 60536 value.  Also, going to a commit
prior to the referenced fix I still don't see any problem on my
machine.  That doesn't rule out a platform-specific manifestation
of the issue, though.
