U+33D8 "㏘" Square Pm Unicode Character
Unicode Version 17.0
㏘
U+33D8 "㏘" Square Pm is a CJK Compatibility Ideograph that represents the unit of measurement picometer, abbreviated as "pm," encoded as a single square symbol for compatibility with legacy East Asian character sets. This character belongs to the CJK Compatibility block, which includes various units and symbols used in Japanese, Chinese, and Korean text processing, allowing a squared representation of the two-letter abbreviation. It is distinct from regular text sequences, designed primarily for compatibility with older systems that treated such units as single characters rather than individual letters, though its usage in modern contexts is rare.
