I didn't intended to introduce non-text internal formats. The original
patch spent some codes to keep all of whitespaces as-is in the input.
But I'd say we can simplify it.

Except whitespaces, normalization of strings and numbers might be
problem when we support JSON comparison operators -- comparison of
Unicode escaped characters in strings or 0 vs. 0.0 in numbers.
