answer:Fonts can be embedded into PDFs (usually a subset of the entire font) so they can be displayed there. When you copy and paste it pulls out the font name along with the text you’re copying but the embedded font data isn’t meant to be transferable as well. It’s a protection for the font, which is considered software and generally has a very limited license. Whitney is from one of the biggest and best known type foundries, Hoefler & Frere-Jones and is mad expensive. If you need something similar but not as costly (and probably already installed) you could find Myriad, Frutiger, or even Gill Sans I think. Haven’t compared them side by side but the same feel. Hope it helps.
