Original PDF text converted to boxes with X's
I created a PDF using Adobe and when I saved it, some letters throughout the file convered to boxes with X's. I have been searching and have not had success, particularly because the new version of Adobe doesn't have the recommended options visible in tools. To be clear, the orignal document I am editing is a PDF -- The problem occurred when saving the PDF -- as a PDF using Adobe. The document has not been converted or exported. How can I get back the original text, removing these boxes with X's?
