Meaning
A lowercase letter i, usually white on a blue square, the international sign for information, like the one at a help desk or tourist office.
It introduces tips, notes, opening hours and anything readers should know before acting: “ℹ️ The museum is closed on Mondays” It sounds neutral and helpful, unlike the urgent ❗ or ⚠️. Many posts place it at the start of a short notice or an FAQ answer.
