Thanks to A2A. First of all let me clarify that a PDF file incorporates both and of a background and in that case an ocr software can recognize the in the image to extract it. I have seen (and used many of them) and they all work pretty well to extract the with just a few errors. On the other hand if the PDF file contains then any PDF viewer such as Foxit PDF Adobe Acrobat Adobe illustrator or even Sumatra PDF will give you the option to select the (by dragging your mouse through) and copy it to the clipboard. Then you can paste it in notepad or MS word or Write or any editor. If you use Adobe acrobat or illustrator both programs can preserve the formatting. Cheers
