U+336F "㍯" Ideographic Telegraph Symbol for Hour Twenty-Three Unicode Character

U+336F "㍯" Ideographic Telegraph Symbol for Hour Twenty-Three is a CJK compatibility ideograph that represents the number 23 in the context of a specific hour of the day, primarily used in older East Asian telegraphy and time-telling systems. It belongs to the CJK Compatibility block, which encodes symbols that were originally included for roundtrip compatibility with legacy character sets, and it corresponds to the Japanese or Chinese way of writing "23" followed by the character for "hour" (時). This symbol is part of a set of 24 telegraph hour symbols, ranging from 0 to 23, that were employed in telegrams and early digital communications to efficiently denote time. While largely obsolete in modern digital text, it remains supported in Unicode for historical and archival purposes.
