U+335B "㍛" Ideographic Telegraph Symbol for Hour Three Unicode Character
U+335B "㍛" Ideographic Telegraph Symbol for Hour Three is a CJK (Chinese, Japanese, and Korean) compatibility ideograph that represents the time 3:00, specifically used in historical telegraph code systems to efficiently transmit times in East Asian contexts. This character is composed of the numeral for "three" (三) and the kanji for "hour" (時), combined into a single square glyph to save space and standardize messaging. It is part of the CJK Compatibility block in Unicode, which preserves these precomposed forms for backward compatibility with older character sets used in Japanese telegraphy and other legacy systems. Today, while rarely needed in modern digital communication, it remains available for encoding historical texts or specialized applications requiring precise representation of telegraphic symbols.
