I’ve been asked to black out text in a PDF document. When I do this in Adobe Acrobat, it appears to be blacked out, but it is only highlighted in black.
The text can therefore still be copied and pasted into notepad etc.
How do I prevent the user from ever being able to see the text?
Its not a font…Its part of Arial which happens to be on most computers. You can also embed fonts in PDFs anyways.
In Windows open Character Map to get access to all the glyphs (Unicode) any font supports.
