  Hi,

  We have a workbook with some special characters in it (e.g. 0xFFFF).
  
  When we save the book using the library it will throw ArgumentException with message “hexadecimal value 0xFFFF is an invalid character.” But we can save the same file with Excel with no problem. Please refer attachment for reproduction.

  Please help to investigate this issue. Thank you.

  Regards
