XlsIO do not have direct support to open an Excel file with encoding in .NET Core. But this can be acheived through below workaround.

C# [Cross-platform]

using (ExcelEngine excelEngine = new ExcelEngine())
{
  IApplication application = excelEngine.Excel;

  FileStream stream = new FileStream("Sample.csv", FileMode.Open, FileAccess.Read);
  System.Text.UnicodeEncoding.RegisterProvider(System.Text.CodePagesEncodingProvider.Instance);
  IWorkbook workbook = application.Workbooks.Open(stream, System.Text.UnicodeEncoding.GetEncoding("big5"));

  FileStream outputStream = new FileStream("Output.csv", FileMode.Create, FileAccess.Write);
  workbook.SaveAs(outputStream, ",");
}
