title: Aurora MySQL Load Data Invalid utf8mb4 character string
body: <p>I am currently using MySQL Aurora 5.7 version.</p>
  <p>I am trying to load data into MySQL with the 'load data' function.</p>
  <p>MySQL's encoding is utf8mb4 and an error occurs when loading the data below.</p>
  <p>Using latin1 encoding solves this problem, but in this case, there is a problem that Hangul is not displayed properly. (Korean Language)</p>
  <p>So I can't use latin1 encoding.</p>
  <p>In this case, what would be best to do it for loading?</p>
  <p>We ask for your help.</p>
