U+1684 "ᚄ" Ogham Letter Sail Unicode Character

U+1684 "ᚄ" Ogham Letter Sail is a character from the Ogham alphabet, an early medieval script used primarily to write the Old Irish and Pictish languages on stone monuments. This specific letter, named "Sail," corresponds to the sound "S" and is traditionally associated with the willow tree in the Ogham tree alphabet lore. Carved along the edge of standing stones, usually reading from bottom to top, the Ogham script was used for inscriptions, names, and boundary markers, and today it is supported for digital representation through Unicode, allowing the preservation and study of this ancient writing system.
