I made a repo as a showcase of this bug https://bitbucket.org/slafs/test-
django-binaryfield-oracle-py3

The test case in this repo is taken from Django testsuite.

The exception i'm getting is this:
{{{
django.utils.encoding.DjangoUnicodeDecodeError: 'utf-8' codec can't decode
byte 0xfe in position 2: invalid start byte. You passed in b'\x00F\xfe'
(<class 'bytes'>)
}}}

The problem is with handling Oracle params in
`django.db.backends.oracle.base.OracleParam` class. I think I may have a
solution on this.

Comment:

Hi, and thanks for your report.

I am looking forward to seeing what you come up with. Please also specify
exactly which Python3 and Oracle versions you are working with -- there
are known Unicode problems related to bugs in certain versions of Oracle
(#20292).

Also, you should be aware that Oracle under Python3 is generally broken
(#20725), so the problem may lie deeper than you think.

Comment:

Some related fixes were introduced in #22715. The Django test-suite passes
on 1.7 and master with python3 and cx_Oracle 5.1.3; so I suspect this has
been solved.

If this is not the case, please reopen.
