title: MySQL tables in Collation latin1_swedish_ci can I just change without impacting PHP code?
body: <p>I setup a MySQL table using Collation latin1_swedish_ci.
  I have coded my PHP scripts in the UTF-8 character-set. It all worked out well until I discovered that a person entered their first name with a non-swedish character.
  The name <strong>Helén</strong> looked strange in the database but looked OK on the webpages.</p>
  
  <p>My question is, can I simply change the Collation of my table from latin1_swedish_ci to UTF-8?</p>
  
  <p>Will it actually cause any problems?</p>
