U+1CEB1 "𜺱" Keyhole Unicode Character

U+1CEB1 "𜺱" Keyhole is a relatively recent addition to the standard, having been encoded in Unicode 16.0 as part of the "Symbols for Legacy Computing Supplement" block. Its designated purpose is to serve as a graphical representation of a keyhole, specifically intended for use in technical documentation, retro computing contexts, or other plain-text environments where a visual icon for a keyed lock or access point is needed. This character allows users to insert a compact, standardized keyhole symbol without relying on images or proprietary fonts, ensuring consistent rendering across compliant systems.
