How do you Parse Symbols

[olakusibe]

I have a PDF which has text, but after extracting text, some part are in text format the rest are in symbols (see screen shot below)
How do I parse this symbols to text ?

I have been having the same issue, the problem isn't specific to PdfPig - every library I have tried has this issue. It seems to occur for me with text that has non-ASCII characters.

The problem is referenced here:

I have a solution of rendering the PDF to images, then performing OCR, however it is not 100% reliable.
