title: How do I reference a field name which includes a slash in Power Query
body: <p>In Excel 2016 Get &amp; Transform ("Power Query") it appears to be totally valid to have a field (column) name containing a slash character. However, when I try to reference this column, I can't find any way to escape the slash to make the reference work. How can I do this?</p>
  
  <p>Specifically, the following code is accepted:</p>
  
  <pre><code>Table.AddColumn(#"Capitalize", "ABC Table", each Table.FromColumns({Text.Split([ABC], ",")}))
  </code></pre>
  
  <p>...but the following is not:</p>
  
  <pre><code>Table.AddColumn(#"Capitalize", "ABC Table", each Table.FromColumns({Text.Split([ABC / DEF], ",")}))
  </code></pre>
  
  <p>...presumably because of the slash in <code>[ABC / DEF]</code>.</p>
  
  <p>How can I escape this slash?</p>
