How to export chinese filename without wrong character?

[eret9616]

    const workbook = new Excel.Workbook();
    workbook.creator = 'xx';
    workbook.lastModifiedBy = 'xx'';
    workbook.created = new Date();
    workbook.modified = new Date();
    const sheet = workbook.addWorksheet('sheet1');
    const columnArr = xxxxx;
    const  r = xxxxx
    sheet.columns = columnArr;
    for (let i = 0; i < r.length; i++) {
      sheet.addRow(r[i]);
    }

    const buffer = await workbook.xlsx.writeBuffer();
    res.set(
      'Content-Type',
      'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
    );
    res.set('charset', 'utf-8');
    res.attachment(`中文名称.xlsx`);
    res.end(buffer);

when i download this file with postman, the character "中文名称" become '----',
i tried res.attachment(encodeURIComponent('中文名称.xlsx')

the filename become
'%E4%B8%AD%E6%96%87%E5%90%8D%E7%A7%B0.xlsx'
