How pytest -k works with Chinese charactors

[jxt-hbtm]

Consider the following example:
data_ids:

SA02722_0001
SA02722_0002
SA02722_0003
SA02651_0001
SA02897_测试1  # The one I want to run.

Test function:

# test_sap.py
... ...
@pytest.mark.parametrize(title_list, data_list, ids=data_ids, scope="function")
def test_main(self, row_num, auth_host, req_host, url, headers, data, expect):

conftest.py:

def pytest_collection_modifyitems(items):
    for i in items:
        i.name=i.name.encode("utf-8").decode("unicode_escape")  # This is important
        print('name: ', i.name)

command line options:

case_expr = '测试'
pytest.main([f'-k {case_expr}', f'--html={test_report_file}', '--self-contained-html', f'--tb={trace_back}', '-q', '-v', 'test_sap.py'])

terminal output:

name:  test_main[SA02722_0001]
name:  test_main[SA02722_0002]
name:  test_main[SA02722_0003]
name:  test_main[SA02651_0001]
name:  test_main[SA02897_测试1]  # This one is selected, as expected.

I don't understand exactly what you are asking. Can you explain what is the problem you ran into?

Thank you.
Actually, there's no problem. It used to be a problem, but I figured it out already.
And It was posted in the 'show and tell' category.
