Comment #7 on issue 1641 by asmeurer: doctests require newline only when
run for single file

Notice how testing simplify before solvers prevents the solvers errors from
being reported.
Now, here is a more important clue. This is what is being run internally:
>>> doc_file1='sympy/solvers/solvers.py'
>>> doc_file2='sympy/simplify/simplify.py'
>>> import doctest as pdoctest
>>> pdoctest.testfile(doc_file2, module_relative=False,
>>> optionflags=pdoctest.ELLIPSIS |
pdoctest.NORMALIZE_WHITESPACE)

As the last line shows, the runner raises UnicodeEncodeError with
solvers.py for some reason. This happens
in line 167 of runtests.py.
