korean language is composed of three parts.
therefore it can't be formatted with 1byte i.e.8 bit.
each everypart has more than 3bit.
therefore (8bit = 2+2+2+2(flag bit)) is not right.
(16bit=1(flag)+5+5+5) is right.
therfore in my point of view, 1byte is impossible
in my thought paging method also not applied.
also compression method is not available.
finally korean language only 2bytes format is available.
in my thought japanese 1byte possible but chinese not available.
chinese also 2bytes available
