I think the EEP should elaborate on normalization. It seems to me that
prescribing NFC would be natural since a file consisting of Latin-1
characters is already NFC (Normalized Form C (Composed)).

O.t.o.h that would make the atom fi⁵ different from the atom fi5,
and using NFKC (Normalized Form KC (Compatibility Composed))
would make them equal. I do not know. That fi =:= fi may be
good but that i⁵ =:= i5 may be not good. Anyway normalizing
these character sequences in comments or strings is _not_
desirable. If NFKC would be an option it could only be that
for atoms and variables.
