Avoid respecifying default encoding for .encode()/.decode() calls

In Python 3, both .encode() and .decode() default the encoding to
'utf-8'. See the docs:

https://docs.python.org/3/library/stdtypes.html#str.encode
https://docs.python.org/3/library/stdtypes.html#bytes.decode

Simplify and shorten the code by using the default instead of
respecifying it.
