How to read pdf having delimiters in it?

[bhoomica virmani <bh...@gmail.com>]

Hi,

I have to modify a template PDF. So, it is like search & replace the content
of PDF.
The template PDF has some characters which are delimiters in pdf like < >
(angular braces), " (curly quotes).
I need to read the PDF without converting the PDF to text.
If I try to read the PDF in terms of tokens, the places where there are
delimiters doesn't read it as string but some wierd symbols like squares.
Can anyone please help me out in reading the delimiters of PDF without
converting it to text?

Thanks
