What ❆ means
It marks winter or frost as decoration.
The Unicode Dingbats collection draws largely on ITC Zapf Dingbats Series 100, a typeface made for printed ornaments. A dingbat is a small decorative sign used in typesetting. Hermann Zapf sketched more than 1,200 signs in 1977; ITC selected a subset for the typeface in 1978.
The set entered Unicode as Zapf Dingbats in 1991 and was renamed Dingbats in 1993. Those dates trace the typeface's path into Unicode, not the first use of this particular snowflake. Its exact outline and weight vary with the font.
Typographic and seasonal, with a decorative rather than conversational tone.
