docs: r"""Transliterate the string into ascii representation.
  
      Transliterate the string contents of the given sequence into ascii
      representation.
      Returns a sequence with the modified values if the module 'unidecode'
      is available. Otherwise it will fall back to the inferior strip_accents
      function.
  
      For example: H\xc3\xb6hne becomes Hohne.
  
      Note: Passed strings are returned as a list.
