Source: Browser Default
U+33D1 "㏑" Square Ln is a CJK compatibility ideograph that represents the mathematical abbreviation for the natural logarithm, typically displayed as the letters "Ln" enclosed within a square box. This character was specifically designed for compatibility with legacy East Asian encoding standards, such as those used in Japanese text processing, where it served as a single glyph to denote the logarithmic function in contexts like scientific notation or technical documentation. While it is rarely used in modern computing, it remains part of Unicode's compatibility set to ensure faithful conversion of older documents.
