What 🆃 means
A stylized T; nearby words tell you what it labels.
“Negative” names the contrast: a light T against a dark square. It is a visual style, not a refusal or mood signal.
Many enclosed letters were designed as lettered list bullets in older East Asian character sets. A wider group of enclosed characters also preserves labels used in Japanese television broadcasting. On 16 September 2009, an international standards proposal asked to fill gaps in the squared and negative-squared Latin-letter sets; it listed 🆃 without a T-specific note.
