Because Unicode has all JIS X 0208 characters in BMP.  However new
standard JIS X 0213:2000 requires surrogate area to represent it.

Since Unicode assigns characters in surrogate area since Unicode-3.1
which is released in 2001, they are not widely used yet.
I agree you, now.  But I think it will be deployed near future.
