Text shown as empty boxes in PDF

[viralr]

Hi. I have attached a sample excel sheet and a pdf generated by Spire .Net. As you can see in the pdf, some of the text has not been converted properly and the pdf shows empty boxes instead of the letters. The text not converted is in Japanese Language.
I am using the below code to do the conversion. Am I missing something in the implementation below or is there an issue with Spire PDF library?

Workbook workbook = new Workbook();
workbook.LoadFromFile(@"c:\temp\temp.xlsx", ExcelVersion.Version2010);
workbook.SaveToFile(@"c:\temp\temp.pdf", FileFormat.PDF);
