"¿" (inverted question mark) character in oracle
<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>
