A lower-case letter i, marking an information point.
Also known as: i symbol, Information point, Letter i in a circle
A letter i marks information. It is a rare case of a letter working as an international pictogram, and it works because the word begins with i in a great many languages — which is also why it fails in those where it does not.
Marks an information desk, kiosk or point where enquiries may be made.

Works across languages because the word for information begins with i in many of them — a coincidence rather than a design, and one that does not hold everywhere.
Contexts: Public information
Carries the same meaning in software interfaces, where an i in a circle marks explanatory detail rather than a physical desk.
