Where does this style work?

It works wherever plain text is accepted — bios, usernames and comments — because the letters are real Unicode characters, not a font.

Can I copy it together with other words?

Yes — copy the whole output and paste it next to plain text; every letter stands alone.

Slanted serif letters, academic look

Serif italic uses the mathematical italic block (𝐴-𝑍, 𝑎-𝑧) — the classic academic italic look, often used for quotes, book titles and elegant names.
