U+336A "㍪" Ideographic Telegraph Symbol for Hour Eighteen Unicode Character

Unicode Version 17.0

U+336A "㍪" Ideographic Telegraph Symbol for Hour Eighteen is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the number 18 in the context of time, specifically the eighteenth hour of the day according to a traditional 24-hour telegraph or clock system. It was originally used in telegrams and early timekeeping formats within East Asian telegraphic codes, where such symbols provided a concise way to encode hour markers. This character is part of a larger set of telegraph symbols for hours one through twenty-four, and it is classified under the Unicode block for CJK Compatibility, meaning it was included to maintain round-trip compatibility with older encoding standards rather than for modern daily use. In contemporary contexts, it is considered a historical or specialized character, rarely employed in standard text but still preserved in Unicode for digital representation of legacy documents.
