I have to read a PDF file using linguagem C and seek a string present in the file. However when pulling the file by function fopen and display it on the screen, it appears all those encoded characters, in the same way when you open the PDF using a text editor, for example.
How do I decode the file and do the parse correct to seek the string? Is there a library, and if possible how to use it ?

You can extract the text contained in the PDF file to then parse. Look at this code.
