[x3d-public] python 2.7 complains about x3d.py

[Andreas Plesch]

$ python
Python 2.7.16 (default, Oct 10 2019, 22:02:15)
[GCC 8.3.0] on linux2

>>> import x3d.x3d as x
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>

SyntaxError: Non-ASCII character '\xc3' in file
/home/andreas/.local/lib/python2.7/site-packages/x3d/x3d.py on line 206,
but no encoding declared; see http://python.org/de
v/peps/pep-0263/ for details

$ cat -nA  /home/andreas/.local/lib/python2.7/site-packages/x3d/x3d.py |
grep 206 | head -1
  206      'SFMatrix3d', # Single Field (singleton) 3M-CM-^W3 matrix of
double-precision floating point numbers$

There are indeed non-ascii characters.

python3 does not complain.
