Normal case

I have this very simple test which is just logging some unicode character:

test_log.py

import logging

logger = logging.getLogger(__name__)

def test():
    logger.info("Normal")
    logger.info("\u251c")
    logger.info("Also normal")

And when I run it using --log-cli-level=INFO then I get this terminal output, which is fine:

============================= test session starts =============================

Save to file

However, when I also run with --log-file=logoutput, this is what I get:

logoutput contents:

test_log.py                  6 INFO     Normal
test_log.py                  8 INFO     Also normal

So it seems that the lines with unicode characters are not getting printed in the log file, which is a problem.

Separated the pytester problem as another issue. For this one (about logging to file) I got a PR.

Update pytest to 3.7.1 (#1247)
This PR updates [pytest](https://pypi.org/project/pytest) from **3.6.2** to **3.7.1**.



<details>
  <summary>Changelog</summary>
  
  
   ### 3.7.1
   ```
   =========================

Bug Fixes
---------

- `3473 &lt;https://github.com/pytest-dev/pytest/issues/3473&gt;`_: Raise immediately if ``approx()`` is given an expected value of a type it doesn&#39;t understand (e.g. strings, nested dicts, etc.).


- `3712 &lt;https://github.com/pytest-dev/pytest/issues/3712&gt;`_: Correctly represent the dimensions of an numpy array when calling ``repr()`` on ``approx()``.

- `3742 &lt;https://github.com/pytest-dev/pytest/issues/3742&gt;`_: Fix incompatibility with third party plugins during collection, which produced the error ``object has no attribute &#39;_collectfile&#39;``.

- `3745 &lt;https://github.com/pytest-dev/pytest/issues/3745&gt;`_: Display the absolute path if ``cache_dir`` is not relative to the ``rootdir`` instead of failing.


- `3747 &lt;https://github.com/pytest-dev/pytest/issues/3747&gt;`_: Fix compatibility problem with plugins and the warning code issued by fixture functions when they are called directly.


- `3748 &lt;https://github.com/pytest-dev/pytest/issues/3748&gt;`_: Fix infinite recursion in ``pytest.approx`` with arrays in ``numpy&lt;1.13``.


- `3757 &lt;https://github.com/pytest-dev/pytest/issues/3757&gt;`_: Pin pathlib2 to ``&gt;=2.2.0`` as we require ``__fspath__`` support.


- `3763 &lt;https://github.com/pytest-dev/pytest/issues/3763&gt;`_: Fix ``TypeError`` when the assertion message is ``bytes`` in python 3.
   ```
   
  
  
   ### 3.7.0
   ```
   =========================

Deprecations and Removals
-------------------------

- `2639 &lt;https://github.com/pytest-dev/pytest/issues/2639&gt;`_: ``pytest_namespace`` has been deprecated.

  See the documentation for ``pytest_namespace`` hook for suggestions on how to deal
  with this in plugins which use this functionality.


- `3661 &lt;https://github.com/pytest-dev/pytest/issues/3661&gt;`_: Calling a fixture function directly, as opposed to request them in a test function, now issues a ``RemovedInPytest4Warning``. It will be changed into an error in pytest ``4.0``.

  This is a great source of confusion to new users, which will often call the fixture functions and request them from test functions interchangeably, which breaks the fixture resolution model.



Features
--------

- `2283 &lt;https://github.com/pytest-dev/pytest/issues/2283&gt;`_: New ``package`` fixture scope: fixtures are finalized when the last test of a *package* finishes. This feature is considered **experimental**, so use it sparingly.


- `3576 &lt;https://github.com/pytest-dev/pytest/issues/3576&gt;`_: ``Node.add_marker`` now supports an ``append=True/False`` parameter to determine whether the mark comes last (default) or first.


- `3579 &lt;https://github.com/pytest-dev/pytest/issues/3579&gt;`_: Fixture ``caplog`` now has a ``messages`` property, providing convenient access to the format-interpolated log messages without the extra data provided by the formatter/handler.


- `3610 &lt;https://github.com/pytest-dev/pytest/issues/3610&gt;`_: New ``--trace`` option to enter the debugger at the start of a test.


- `3623 &lt;https://github.com/pytest-dev/pytest/issues/3623&gt;`_: Introduce ``pytester.copy_example`` as helper to do acceptance tests against examples from the project.



Bug Fixes
---------

- `2220 &lt;https://github.com/pytest-dev/pytest/issues/2220&gt;`_: Fix a bug where fixtures overridden by direct parameters (for example parametrization) were being instantiated even if they were not being used by a test.


- `3695 &lt;https://github.com/pytest-dev/pytest/issues/3695&gt;`_: Fix ``ApproxNumpy`` initialisation argument mixup, ``abs`` and ``rel`` tolerances were flipped causing strange comparsion results.
  Add tests to check ``abs`` and ``rel`` tolerances for ``np.array`` and test for expecting ``nan`` with ``np.array()``


- `980 &lt;https://github.com/pytest-dev/pytest/issues/980&gt;`_: Fix truncated locals output in verbose mode.



Improved Documentation
----------------------

- `3295 &lt;https://github.com/pytest-dev/pytest/issues/3295&gt;`_: Correct the usage documentation of ``--last-failed-no-failures`` by adding the missing ``--last-failed`` argument in the presented examples, because they are misleading and lead to think that the missing argument is not needed.



Trivial/Internal Changes
------------------------

- `3519 &lt;https://github.com/pytest-dev/pytest/issues/3519&gt;`_: Now a ``README.md`` file is created in ``.pytest_cache`` to make it clear why the directory exists.
   ```
   
  
  
   ### 3.6.4
   ```
   =========================

Bug Fixes
---------

- Invoke pytest using ``-mpytest`` so ``sys.path`` does not get polluted by packages installed in ``site-packages``. (`742 &lt;https://github.com/pytest-dev/pytest/issues/742&gt;`_)


Improved Documentation
----------------------

- Use ``smtp_connection`` instead of ``smtp`` in fixtures documentation to avoid possible confusion. (`3592 &lt;https://github.com/pytest-dev/pytest/issues/3592&gt;`_)


Trivial/Internal Changes
------------------------

- Remove obsolete ``__future__`` imports. (`2319 &lt;https://github.com/pytest-dev/pytest/issues/2319&gt;`_)

- Add CITATION to provide information on how to formally cite pytest. (`3402 &lt;https://github.com/pytest-dev/pytest/issues/3402&gt;`_)

- Replace broken type annotations with type comments. (`3635 &lt;https://github.com/pytest-dev/pytest/issues/3635&gt;`_)

- Pin ``pluggy`` to ``&lt;0.8``. (`3727 &lt;https://github.com/pytest-dev/pytest/issues/3727&gt;`_)
   ```
   
  
  
   ### 3.6.3
   ```
   =========================

Bug Fixes
---------

- Fix ``ImportWarning`` triggered by explicit relative imports in
  assertion-rewritten package modules. (`3061
  &lt;https://github.com/pytest-dev/pytest/issues/3061&gt;`_)

- Fix error in ``pytest.approx`` when dealing with 0-dimension numpy
  arrays. (`3593 &lt;https://github.com/pytest-dev/pytest/issues/3593&gt;`_)

- No longer raise ``ValueError`` when using the ``get_marker`` API. (`3605
  &lt;https://github.com/pytest-dev/pytest/issues/3605&gt;`_)

- Fix problem where log messages with non-ascii characters would not
  appear in the output log file.
  (`3630 &lt;https://github.com/pytest-dev/pytest/issues/3630&gt;`_)

- No longer raise ``AttributeError`` when legacy marks can&#39;t be stored in
  functions. (`3631 &lt;https://github.com/pytest-dev/pytest/issues/3631&gt;`_)


Improved Documentation
----------------------

- The description above the example for ``pytest.mark.skipif`` now better
  matches the code. (`3611
  &lt;https://github.com/pytest-dev/pytest/issues/3611&gt;`_)


Trivial/Internal Changes
------------------------

- Internal refactoring: removed unused ``CallSpec2tox ._globalid_args``
  attribute and ``metafunc`` parameter from ``CallSpec2.copy()``. (`3598
  &lt;https://github.com/pytest-dev/pytest/issues/3598&gt;`_)

- Silence usage of ``reduce`` warning in Python 2 (`3609
  &lt;https://github.com/pytest-dev/pytest/issues/3609&gt;`_)

- Fix usage of ``attr.ib`` deprecated ``convert`` parameter. (`3653
  &lt;https://github.com/pytest-dev/pytest/issues/3653&gt;`_)
