Read PDF table when save to txt issue

Hi All,

I would like to know read pdf text and save as txt, for table, why some table between column contains “|”, while others don’t .
txt content:

Subject this is nt even a real thing on an invoice
Description | Quantity | Unit Price | Amount
description of number one product | 12 | 1,222.00 | 14,664.00
the second product | 1,111 | 12.00 | 13,332.00
the third description of some service | 1 | 2,000.00 | 2,000.00

can use like below
line.ToString.Split({“|”},StringSplitOptions.None)

%E5%9B%BE%E7%89%87

How I can get the data is txt not contain"|"?


Any sugguestions?
