title: What characters are allowed by dojo's query function?
body: <p>I plan to use dojo.query to get some elements by their name attribute from a page. However, since the value of name comes from the back-end, there might be some illegal characters, like <code>+</code>, <code>!=</code> and so on.</p>
  
  <p>Is there a list of what characters are allowed? I plan to replace the invalid ones with "" via Regular Expressions.</p>
