U+3360 "㍠" Ideographic Telegraph Symbol for Hour Eight Unicode Character
U+3360 "㍠" Ideographic Telegraph Symbol for Hour Eight is a specialized CJK (Chinese, Japanese, and Korean) symbol that represents the eighth hour in a telegraph or telecommunication context. Originally part of the code used in telex and telegraph systems across East Asia, it condenses the ideograph for eight and the character for hour into a single compact unit. This character belongs to the CJK Compatibility block in Unicode, which was designed to encode precomposed forms used in older standardized character sets, such as those for train timetables or weather reports. While rarely used in modern digital text, it remains a functional element for historical data processing and ensures compatibility with legacy systems that require precise hour markers.
