WorkSheet.Cells[RowNum, ColNum].PutValue("\u00FC");
columnStyle.Font.Name = “Wingdings”;
columnStyle.Font.Charset = 2;
WorkSheet.Cells.ApplyColumnStyle(ColNum, columnStyle, column.Style.StyleFlag);
This is not working; Instead the font gets defaulted to Arial 10. I’ve also tried Charset 0 and 1. I’m saving as an xlsx.
