Description

I use the HtmlTESTRunner, it reports the follow error.
Becouse of my testcase is output the conent like "[{'Text': 'æ\x96°å\x91\x98å·¥å\x85¥è\x81\x8c', ...}]"
so I modify the code of HTMLTESTRunner/result.py in 404, as "with open(path_file, 'w', encoding='utf-8') as report_file:", its running is ok!
Is this line code need to modify?
