title: Adding tilde to datawindow setFilter string
body: <p>I've been trying to filter a datawindow by using the argument <code>product_id = 'Z108-20-6,3~10' and company_id = 14</code>, but the setFilter function returns -1, which is invalid. </p>
  
  <p>After looking at the docs and some Google search, I've found that the tilde character is an escape character, so, in order to use it as a literal character, I should be using "~~" instead of "~". Using two tildes in the filter argument does change the return value, but doesn't apply the filter correctly (it keeps showing no rows).</p>
  
  <p>How can I SetFilter a datawindow by using a tilde in the filter expression? I`m using PB 12.5.</p>
