Joe Tsai 78805c07f4 archive/zip: restrict UTF-8 detection for comment and name fields ... CL 39570 added support for automatically setting flag bit 11 to indicate that the filename and comment fields are encoded in UTF-8, which is (conventionally) the encoding using for most Go strings. However, the detection added is too lose for two reasons: * We need to ensure both fields are at least possibly UTF-8. That is, if any field is definitely not UTF-8, then we can't set the bit. * The utf8.ValidRune returns true for utf8.RuneError, which iterating over a Go string automatically returns for invalid UTF-8. Thus, we manually check for that value.
