title: jqgrid colmodel title does not display UTF-8 characters properly
body: <p>jqgrid displays garbled characters when I hover over the cell data for UTF-8(for example chinese) characters. But the grid displays the data correctly. Is it a limitation or is there a way to display the data correctly in the title/tooltip?</p>
  
  <p>Head section has content-type set correctly.
  &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"/&gt;</p>
