U+33F4 "㏴" Ideographic Telegraph Symbol for Day Twenty-One Unicode Character

Unicode Version 17.0

U+33F4 "㏴" Ideographic Telegraph Symbol for Day Twenty-One is a typographic representation used in Japanese telegraphy and older coded messaging systems to denote the 21st day of a month. This character is part of a larger block of CJK Compatibility symbols that were included in Unicode to support legacy text encoding from the Japanese telegraph code, where each day of the month was assigned a unique symbol. The glyph itself combines the kanji-like characters for "twenty" and "one," reflecting the number 21 in a compact, standardized form. While largely historical in origin, this symbol may still appear in certain archival documents or specialized digital texts that preserve traditional encoding formats.
