Sigh. From the first day when JOHAB was supported (back to 7.3 days),
it should had not been in the server encodings. JOHAB's second byte
definitely contain 0x41 and above. *johab*.map just reflect the
fact. I think we should remove JOHAB from the server encodings list.
I'm afraid users who have JOHAB encoded databases get angry, though.
