Unicode shouldn't have allowed multiple equivalent variants for a
string.

Now Python falls victim to:

   >>> '\u006e\u0303' == '\u00f1'
   False

<URL: https://en.wikipedia.org/wiki/Unicode_equivalence>:

   For example, the code point U+006E (the Latin lowercase "n") followed
   by U+0303 (the combining tilde "◌̃") is defined by Unicode to be
   canonically equivalent to the single code point U+00F1 (the lowercase
   letter "ñ" of the Spanish alphabet). Therefore, those sequences
   should be displayed in the same manner, should be treated in the same
   way by applications such as alphabetizing names or searching, and may
   be substituted for each other.
