What 🡁 means
It points upward; “heavy compressed” describes its drawing. A 2011 Unicode proposal records its Wingdings source glyph as w-3195. Wingdings is a font that displayed symbols in place of ordinary letters; the proposal groups this glyph with matching heavy, compact arrows pointing in three other directions. Unicode later encoded the design as text.
