title: Is it possible to insert hexa values in a SQL query?
body: <p>I have a form that takes names (in natural language) as default argument and compare those to a table of users.</p>
  
  <p>Is it possible to send those names in their hexadecimal value equivalent ? Example: for user "sam" i would send <code>0x730x610x6d</code> or <code>0x73616d</code>, but neither of them works. </p>
  
  <p>Any idea ?</p>
  
  <p>p.s: in my target page for this form, i defined <code>'charset'</code> parameter as <code>"utf8"</code></p>
