title: MySQL Error Code: 1300. Invalid utf8 character string: '' with '\' infront of unicode character
body: <p>I have a bunch of csv-files and I came across a case where strangely enough '\' utf8 are in front of unicode characters e.g.</p>
  
  <pre><code>Tom;\Éscobar;123
  </code></pre>
  
  <p>and when doing a bulk insert via:</p>
  
  <pre><code>LOAD DATA LOCAL INFILE 'test.csv'
  INTO TABLE TEST_TABLE
  CHARACTER SET 'utf8'
  FIELDS TERMINATED BY ';'
  ENCLOSED BY '"';
  </code></pre>
  
  <p>the error: Invalid utf8 character string: '' is thrown.
  I wonder if this is a bug in MySQL LOAD DATA or if I am missing something here.</p>
  
  <pre><code>MySQL-Version 5.7.16
