U+3326 "㌦" Square Doru Unicode Character

U+3326 "㌦" Square Doru is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the Japanese word "doru," which is derived from the English word "dollar." This character is part of a block of squared katakana letters used in East Asian typography, specifically designed to fit neatly within a square space for compatibility with older text encoding systems. It functions as a single character symbol for the currency unit, commonly appearing in Japanese text to denote the U.S. dollar or other dollar-based currencies, much like the dollar sign ($) but adapted for vertical writing and monospaced layouts.
