I'm seeing weird extra glyphs while printing unicode
$ python3
Python 3.6.7 (default, Dec 5 2018, 15:01:38)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux

>>> print("\N{snake}")

This is what it looks like in the terminal:
The unwanted character appears to be REPLACEMENT CHARACTER, ord 0xfffd.
>>> import locale, sys, os
>>> sys.stdout.encoding
'UTF-8'
>>> locale.getdefaultlocale()
('en_US', 'UTF-8')
>>> os.environ["LANG"]
'en_US.UTF-8'
>>> sys.getdefaultencoding()
'utf-8'
What can cause that and how to fix it? Any other details you'd like provided let me know in comments and I'll edit them in.
