U+1D591 "𝖑" Mathematical Bold Fraktur Small L is a typographic symbol belonging to the Mathematical Alphanumeric Symbols block, designed for use in mathematical notation where a bold Fraktur style is required. It represents a lowercase letter L in a blackletter script that combines the heavy weight of bold type with the ornate, medieval-inspired Fraktur form.
