Did you even read my comment? The "application" is called pdftotext, and instead of putting the individual letters on a bitmap, it puts them in a string literal.

I do not understand why you insist on being polemic to win an internet argument, when I'm giving you all the tools to win the internet argument by virtue of being correct.

I did read your comment, because my intention here is to learn. I already described how tools such as pdftotext do not produce strings when each letter is positioned independently. I even gave an example of a few replies up.
