Because it's a very fast conversion; the single byte form just
encodes the ku / ten (row / column) with some bitshifts etc;
converting to other kuten-based encodings (Big5 etc) is then also
very simple. But there is no simple mapping from kuten to Unicode,
I think you'd need an 8000-entry table (and one to map back). I
also believe there are a few codepoints that don't have a one-to-one
mapping to Unicode, so a roundtrip conversion isn't guaranteed.
