Yes.  And mixed encodings is not the only use case: it may well happen
that the initial attempt to decode the file uses incorrect assumption
about the encoding, for some reason.

In addition, it is important that changing some portion of the file,
then saving the modified text will never change any part that the user
didn't touch, as will happen if invalid sequences are rejected at
input time and replaced with something else.
