title: Wordpress question mark black diamonds
body: <p>i don't know why but some (not all) accents become black diamonds with question mark inside.
  This problem drive me crazy.
  My MySQL Database is utf-8 character and utf-8_general_ci collate.
  I use charset utf-8 but if last character is an accent become a black diamond.
  I really don't know why.</p>
  
  <p>For example</p>
  
  <p>Title: CTX-21 Alka + Incrementatore di alcalinità
  Become: CTX-21 Alka + Incrementatore di alcalinit�</p>
  
  <p>Title: Title: CTX-21 Alka + Incrementatore di alcalinità.
  Become: Title: CTX-21 Alka + Incrementatore di alcalinità.</p>
