title: What's the effect of Warning: (1366, "Incorrect string value: '\\xF0\\x9F\\x92\\xA5Th...' for column 'text' at row 1")
body: <p>I am streaming tweets into MySQL database. I read lots of other questions and I know what have caused this warning but I don't understand the effect of this. Is it case 1: This whole single tweet wasn't successfully added to the database</p>
  
  <p>or case 2: The recognizable part of this tweet is added to the database, only the part that is not recognizable is left out.</p>
  
  <p>How can I make sure about this? Is there anything like a log that I can read?</p>
