U+3362 "㍢" Ideographic Telegraph Symbol for Hour Ten Unicode Character

U+3362 "㍢" Ideographic Telegraph Symbol for Hour Ten is a legacy encoding used in the original Japanese telegraph system, where it compactly represents the kanji compound for "ten o'clock" (十時, pronounced "jū-ji"). It belongs to the "CJK Compatibility Ideographs" block, originally standardized for vertically formatted telegraph messages in East Asian communication systems, and is now considered a historic numeric notation rather than a modern writing symbol. As a compatibility character, it is included primarily for round-trip conversion with older encoding standards and is distinct from ordinary kanji or Chinese characters, functioning as a single celled symbol equivalent to writing the time "10:00" in shorthand.
