title: How to combine unicode subscript with string formatting
body: <p>I am trying to get unicode subscripts working with string formatting...
  I know I can do something like this...</p>
  
  <pre><code>&gt;&gt;&gt;print('Y\u2081')
  Y₁
  &gt;&gt;&gt;print('Y\u2082')
  Y₂
  </code></pre>
  
  <p>But what i really need is something like this since I need the subscript to iterate over a range.  Obviously this doesn't work though.</p>
  
  <pre><code>&gt;&gt;&gt;print('Y\u208{0}'.format(1))
    File "&lt;ipython-input-62-99965eda0209&gt;", line 1
      print('Y\u208{0}'.format(1))
           ^
  SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 1-5: truncated \uXXXX escape
  </code></pre>
  
  <p>Any help appreciated</p>
