title: Lua String replace
body: <p>How would i do this?</p>
  
  <p>I got this:</p>
  
  <pre>
  name = "^aH^ai"
  string.gsub(name, "^a", "")
  </pre>
  
  <p>which should return "Hi", but it grabs the caret character as a pattern character</p>
  
  <p>What would be a work around for this? (must be done in gsub)</p>
