Description
A point and a vertical line above it.

In several computer fonts, the vertical line forms a thin acute angle, being slightly larger at the top than the bottom. It may also be rounded at the top.

Etymology
May derive from a Latin Io, with the I written over the o, placed at the end of an exclamation to mark it as such. The Io may either be an abbreviation for, or else the interjection. It expresses admiration in the sentence clause(s), in the Latin sense, of awe or wonderment.
