U+1FBFA "🯺" Alarm Bell Symbol Unicode Character

Unicode Version 17.0

🯺

U+1FBFA "🯺" Alarm Bell Symbol is a relatively recent addition to the Unicode standard, having been included in version 14.0 released in September 2021 as part of the Symbols for Legacy Computing supplement block. This character depicts a stylized alarm bell and was primarily intended for use in retro computing contexts, often representing an audio alarm or alert signal in terminal emulators, early computer interfaces, or teletype systems where such a specific graphical symbol was historically needed. Its design is distinct from the more common emoji bell (U+1F514) and serves a more technical, functional purpose rather than a decorative or emotional one, making it a niche but useful glyph for programmers, historians, and enthusiasts working with legacy computing documentation or digital archaeology.
