In ubuntu18.04 version, the cell text in the pdf table is too long and an error will be reported

Document doc = new Document();
Page page = doc.Pages.Add();
Table table = new Table() { ColumnWidths = “450” };
table.Rows.Add().Cells.Add(“Condition: hydrogenchloride;sodium hydrogencarbonate;Sealed” +
“Procedure: Example 31 4 - (3 - Bromo - phenyl) - 2 - methyl - 8 - trifluoromethyl - quinazoline To a stirred solution of(2 - amino - 3 - (trifluoromethyl)phenyl)(3 - bromo - phenyl)methanone(1.rifluoromethyl - quinazoline To a stirred solution of(2 - amino - 3 - (trifluoromethyl)phenyl)(3 - bromo - phenyl)methanone(1.00 g, 2.9 mmol), in acetonitrile(15 mL) a t 0°C.was bubbled HCl(gas) until saturation.The vessel was sealed and heated for 14 h at 50°C.After 14 h the reaction was cooled and concentrated in vacuo to give an oily residue, which was take n up in NaHCO3 solution(sat) and extracted with ethyl acetate(2*50 mL).

doc.Save(ms, SaveFormat.Pdf);

When I use this code to execute it on Linux, the following error will be prompted.

I hope this problem can be resolved as soon as possible. This problem appears in the PDF20.11.0 version, and the previous versions also have this problem
