In `@README.md` at line 397, Remove the garbled terminal/encoding artifact "ECHO��
�����Ǿ� �ֽ��ϴ�." found at the end of README.md (the text shown in the diff) so
the file ends cleanly; ensure you delete that line, trim any trailing blank
lines or whitespace, and save the README.md with UTF-8 encoding to prevent
reintroducing encoding artifacts.
