title: JQgrid - escape ':' in searchoptions (value part)
body: <p>How to set the values for filter is explained here <a href="http://www.trirand.com/jqgridwiki/doku.php?id=wiki:search_config" rel="noreferrer">link text</a>. I have two requirements.<br>
  1. the default value needs to be empty. I expect, if defaultValue is not set, the filter is empty, but that is not happening in my case.<br>
  2. How to escape ':' in my value. The character ':' and ';' are used to seperate the index and values. But, in my value string it contains a ':' (eg: searchoptions:{value:"1:'Level: 1'"} , where Level: 1 is my first value). How to escape : in the value part. I tried \ , / etc.   </p>
  
  <p>thanks.  </p>
  
  <p>Edit: Item 1 may be solved if there is no other way. I may set an additional item ALL in the values, and use it default.</p>
