title: Danger of switching prestashop database from utf8 to utf8mb4 to get access to emoticons?
body: <p>With the arrival of the display of emoticons in Google searches, I wanted to make my own tests by embellishing a few meta_title to see if it could have a positive effect for our site.</p>
  
  <p>Unfortunately, after saving my meta_title change with the special character, no get no error message but the field is now empty on both prestashop and the database.</p>
  
  <p>And for good reason, the encoding in the database in utf8 instead of utf8mb4.</p>
  
  <p>So I modified the encoding of the column as well as the table for which I wanted to have access to the special characters but they are transformed after "???".</p>
  
  <p>It seems that I would have to change the encoding of the database itself and that's my question:</p>
  
  <p><strong>Do you know if there is any contraindication to switch the prestashop database from utf8 to utf8mb4?</strong></p>
  
  <p>I'm afraid there may be a loss of data somewhere in the database.</p>
  
  <p>I am interested in all the information on the subject.</p>
  
  <p>Thank you in advance.</p>
