title: Possibilty to use Unicode Blocks (\p{InBasic_Latin}) in regex built-in of Python 3.7 to match canonical equivalence
body: <p>In order to write a shorter regex expression and precise one, I want to know the possibility to use unicode blocks as shown <a href="https://www.regular-expressions.info/unicode.html#prop" rel="nofollow noreferrer">here</a>. </p>
  
  <p>The problem when I try to use <code>'\p{InBasic_Latin}'</code> with regex built-in is the returned error <code>re.error: bad escape \p at position ...</code></p>
  
  <p>Is it possible to use unicode blocks with python 3.7's regex?</p>
