Total read byte count; used for error reporting purposes

_surrogate
Although input is fine with full Unicode set, Java still uses
16-bit chars, so we may have to split high-order chars into
surrogate pairs.

LAST_VALID_UNICODE_CHAR
JSON actually limits available Unicode range in the high end
to the same as xml (to basically limit UTF-8 max byte sequence
length to 4)

Although this method is implemented by the base class, AND it should
never be called by main code, let's still implement it bit more
efficiently just in case
