📷 错误截图

Start by reproducing the command in the issue, then read media_platform/douyin/help.py and media_platform/douyin/client.py around get_a_bogus_from_js and __process_req_params. Trace how execjs invokes the signing function on Windows and verify the search command completes without the reported UnicodeEncodeError.
