The generated HTML looks like this:

  <span class='w0'>E</span>
  <span class='w1'>n</span>
  <span class='w2'>t</span>
  <span class='w3'>e</span>
  <span class='w4'>r</span>
  <span class='w5'> </span>
  <span class='w6'>t</span>
  <span class='w7'>e</span>
  <span class='w8'>x</span>
  <span class='w9'>t</span>
  ...

I don't see why that would be a problem.
