U+33EC "㏬" Ideographic Telegraph Symbol for Day Thirteen Unicode Character
Unicode Version 17.0
㏬
U+33EC "㏬" Ideographic Telegraph Symbol for Day Thirteen is a specific code point within the CJK Compatibility block, originally used in historical telegraph code systems to represent the thirteenth day of a month in a single, compact character. This symbol belongs to a set of twenty-four ideographic telegraph symbols for days, which were employed in older East Asian telecommunication technologies to avoid ambiguity and save space in coded messages. While largely obsolete today due to modern digital encoding, it remains in Unicode for compatibility with legacy data and is visually composed of the Chinese character for "thirteen" surrounded by a stylistic telegraph enclosure.
