title: "¿" (inverted question mark) character in oracle
body: <p>I found "<code>¿</code>" character (inverted question mark) in the database tables in place of single quote (<code>'</code>) character.</p>
  
  <p>Can any one let me know how i can avoid this character from the table.</p>
  
  <p><em>There are many rows which contains the text with this character but not all single quotes are turning to this ¿ symbol.</em></p>
  
  <p>I am not even able to filter the rows to update this character (¿) with single quote again.</p>
  
  <p>When i user Like "%¿%" it filters me the text containing ordinary question mark (?)</p>
