docs: Return ``True`` if the IPA character is equivalent to the ``other`` object.
  
          The ``other`` object can be:
  
          1. a Unicode string, containing the representation of the IPA character,
          2. a Unicode string, containing a space-separated list of descriptors,
          3. a list of Unicode strings, containing descriptors, and
          4. another IPAChar.
