title: Escape the * character in KDB SQL "like" queries
body: <p>I have a scenario where I have data in my KDB table that contains multiple consecutive asterisk characters in a string, and I need to be able to search for that string. Suppose the string I'm searching for is <code>foo**bar</code>, the query I'd want to write is:</p>
  
  <pre><code>select from table where column like "foo**bar" 
  </code></pre>
  
  <p>I need to escape the * characters, but I can't find in the docs how to do that. I've tried backslash and a couple of other variants without success. Presumably this must be possible?</p>
