Are you certain the request contains correct headers for files? In
particular, look at the “Content-Disposition” header; for each file,
it should contain the “filename” attribute; otherwise, Django will
treat it as a regular (non-file) form field [1]. As an example, the
header could look like this::
Content-Disposition: form-data; name="file"; filename="filename.png"

By this point, it's too late – Django has already treated the field as
a string field, so it's already called
``force_text(data, encoding, errors='replace')`` [2], which means the
value you have there has already lost some information that is
impossible to get back [3].
And even if it was reversible, performing a Unicode normalization, and
then throwing away everything non-ASCII would most certainly not be
the correct way, since it would mangle about one half of the input
data into ASCII.

You'll have to make sure that the request is correct, I'm afraid.
Good luck,
