splitter.extract_chosung       # => 'ㅎ'
splitter.extract_jungsung      # => 'ㅢ'
splitter.extract_jongsung      # => 'ㄳ'
splitter.split                 # => ['ㅎ', 'ㅢ', 'ㄳ']

# 종성이 없는 경우는 nil
splitter2 = Ununiga::JasoSplitter.new('가')
splitter2.extract_jongsung     # => nil
splitter2.split                # => ['ㄱ', 'ㅏ', nil]
