Python pytest是否在测试名称中支持unicode？

这是我的测试样本（test_time.py）：

以下是pytest输出：

============================================================================== FAILURES ==============================================================================
_________________________________________________________________ test_timedistance_v1[\u4e2d\u6587] _________________________________________________________________

a = datetime.datetime(2001, 12, 12, 0, 0), b = datetime.datetime(2001, 12, 11, 0, 0), expected = datetime.timedelta(1)

    @pytest.mark.parametrize("a,b,expected", testdata, ids=[u"中文", u"English"])
    def test_timedistance_v1(a, b, expected):
        diff = a - b
>       assert diff != expected
E       assert datetime.timedelta(1) != datetime.timedelta(1)

test_time.py:15: AssertionError
___________________________________________________________________ test_timedistance_v1[English] ____________________________________________________________________

a = datetime.datetime(2001, 12, 11, 0, 0), b = datetime.datetime(2001, 12, 12, 0, 0), expected = datetime.timedelta(-1)

    @pytest.mark.parametrize("a,b,expected", testdata, ids=[u"中文", u"English"])
    def test_timedistance_v1(a, b, expected):
        diff = a - b
>       assert diff != expected
E       assert datetime.timedelta(-1) != datetime.timedelta(-1)

test_time.py:15: AssertionError
====================================================================== 2 failed in 0.05 seconds ======================================================================

对于输出中的第二行，测试名称是“test_timedistance_v1[\u4e2d\u6587]”，我希望它是“test_timedistance_v1”[中文]"， py.test支持它吗？

（我的pytest版本是3.1.2，OS:macOS 10.12.5）

它不取决于pytest，而是取决于您的计算机区域设置

这里是测试的跟踪日志（LC_ALL=“en_US.UTF-8”）：

在OS X上设置您的区域设置的有用链接。

刚刚找到，看起来还不受支持。我已尝试将LC_ALL&LANG导出到en_US.UTF-8 | zh_CN | zh_CN.UTF-8 | C.UTF-8，这一切都不起作用。可能它只在Linux平台上起作用。
