title: Is ≤ a legit less than equals char?
body: <p>I was reading the release notes of Visual Studio Code and a particular caught my eye.</p>
  
  <p><img src="https://i.stack.imgur.com/FarFC.png" alt="Screenshot from the release notes"> </p>
  
  <p>As you can see, there is a javascript file with the ≤ symbol.
  I can't figure out how it works, if I try to use it in my code I get a "Invalid or unexpected token" error (which I was expecting), and I can't find if it's only a VSCode configuration that shrinks &lt;= into ≤ for aesthetic purposes.</p>
  
  <p>How does it work?</p>
