In https://docs.python.org/3/library/calendar.html#calendar.LocaleTextCalendar I read "If this locale includes an encoding all strings containing month and weekday names will be returned as unicode."

`unicode` here is a mention of the `unicode` type from Python 2 which does no longer exists, so the whole sentence can just be removed.

It happen also in the next paragraph, and twice in Lib/calendar.py.

In Python 2:

>>> print type(calendar.LocaleTextCalendar(locale="C").formatmonth(2020, 1))
<type 'str'>
>>> print type(calendar.LocaleTextCalendar(locale="en_US.UTF8").formatmonth(2020, 1))
<type 'unicode'>

In Python 3:

>>> print(type(calendar.LocaleTextCalendar(locale="C").formatmonth(2020, 1)))
<class 'str'>
>>> print(type(calendar.LocaleTextCalendar(locale="en_US.UTF8").formatmonth(2020, 1)))
<class 'str'>

I would like to take this issue.

Can i take on this issue? If yes, what am I supposed to do except for removing those lines which are mentioned?

The open PR updates the docstrings in Lib/calendar.py but the corresponding changes in Doc/ still need to be added.
