Issue #21398: Fix an unicode error in the pydoc pager when the documentation

(Merge 3.4)
STINNER Victor added the comment:
I fixed the initial bug and so I close the issue.
Open a new issue if you have an idea to restore the terminal state when the
pager breaks the terminal. I don't think that it's possible to save/restore the
terminal state in a portable way.

LC_CTYPE=C: pydoc leaves terminal in an unusable state
In the use case, pydoc doesn't touch the terminal, it's the pager: the program
less. I don't see how to ensure that the terminal state is restored, even on
error.

Python2 suppresses the exception until after normal exit (pressing 'q').
I think that behavior is better.
In Python3 you can also get the
STINNER Victor added the comment:
heapq documentation contains François which is not encodable to ASCII. When
using LC_ALL=C, the locale encoding is ASCII (at least on Linux). It's not easy
to specify a different error handler globally in pydoc, different functions are
used and child
Stefan Krah added the comment:
The patch works well BTW. We can create another issue for the
general misbehavior of pydoc with other exceptions.

Ah, yes, my lc_ctype was en_US.utf-8. I can reproduce it if I change that.

I use OSX 10.9 on my laptop, Python 3.5 and I get this error in one case. If I
use CTRL-C to quit the application and if LC_CTYPE=C.
with the 'q' key, I don't get this problem.
Just LC_CTYPE=C and CTRL-C and I have to reset my terminal.

Stefan Krah added the comment:
I can also confirm the need to reset the terminal when using
a working locale and Ctrl-C.
So we have two issues then:
1) The UnicodeDecodeError should not happen.
2) pydoc behaves erratically after various exceptions.
In Python2.7 neither of the issues
Stéphane Wirtel added the comment:
In python 2.7, If I use my working locales (utf-8) and I use CTRL-C, pydoc does
not quit but leave a message when the screen is cleaned.
same result with LC_CTYPE=C
