There aren't any 8-bit characters there, unless those "k"s are really "k
with the 8th bit turned on"; rubout isn't an 8-bit character - it has
the bottom seven bits turned on, but not the 8th bit.

Also, SunOS ain't BSD; the checks for 8-bit characters were removed from
the SunOS file system code in 4.0.
