In the test, this is intentional. In praxi, utf-16 is recognized by the BOM and correctly decoded, if the "input_encoding" setting is left at its default (None).

See [feature-requests:#92].

** [bugs:#436] docutils doesn't build with Python 3.11**

Hello,

in Fedora we started with rebuilding Python packages with preleases of Python 3.11, currently it is 2nd alpha. 

Docutils doesn't build because 3.11 adds support for null characters in the csv module, which breaks a test. See reproducer below.

>>> import csv
>>> from docutils.parsers.rst.directives import tables
>>> with open('utf-16.csv', 'rb') as f: csv_data = f.read()
... 
>>> csv_data = str(csv_data, 'latin1').splitlines()
>>> reader = csv.reader([tables.CSVTable.encode_for_csv(line + '\n') for line in csv_data])
>>> next(reader)

Python 3.11:

['þÿ\x00"\x00T\x00r\x00e\x00a\x00t\x00"\x00', '\x00 \x00"\x00Q\x00u\x00a\x00n\x00t\x00i\x00t\x00y\x00"\x00', '\x00 \x00"\x00D\x00e\x00s\x00c\x00r\x00i\x00p\x00t\x00i\x00o\x00n\x00"\x00']

Python 3.10:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
_csv.Error: line contains NUL
