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.

Dot under every letter

Dotted adds a combining dot below (U+0323) to every letter — subtle decorative texture.
