title: Mysql: Set column charset
body: <p>I have an existing table and I want to convert the charset only for one specific column to utf-8.</p>
  
  <p>I know that this command <code>ALTER TABLE table_name CONVERT TO CHARACTER SET utf8</code> does it for the whole table but I'm looking for a column-specific command. </p>
  
  <p>Is there a command for that?</p>
