Description of problem:
Through jko's explaination, understand that vowel always combine with consonent
and vowel by itself has no meaning. Currently IME allows user to enter vowel
follow by a consonent, the end result may not be ideal. For example,

const R + vowel H = ê³  (correct)
vowel H + const R = ê³  (correct however, in alternative OS, it is represented as
,ãã±, 2 distinct chars)

RMR + const R + vowel M =극그(correct)
RMR + vowel M + const R =그극(incorrect)
