Considering that with 2chan style tripcodes, the unicode input is
converted to shift-jis, using anything other than SJIS is pointless as
far as tripcodes are concerned.

I remember reading that on the mailing list somewhere. That's what
makes DES 56 bit correct? Only the lowest 7 bits of the first 8
characters are used.
