<bot>: Here is a Python code to create a set default encoding ansi

import sys

def set_default_encoding(encoding):
  """Set default encoding to the given encoding.
  If encoding is None, the default encoding is set to UTF-8.
  """
  if encoding is None:
    encoding = 'utf-8'
  return encoding

# Enter the encoding
encoding = 'utf-8'

# Calling the function
print((set_default_encoding(encoding)))

#Example Output
# utf-8

#Remember to inspect code for bugs.
