Show HN: A custom font that displays Cistercian numerals using ligatures

Type a number and watch it transform into a forgotten medieval numeral system.

Deep Dive

A developer has created a custom font that automatically converts typed numbers into Cistercian numerals, a compact, line-based system used by medieval European monks. By using font ligatures, typing '123' instantly renders the corresponding historical symbols. The font works in web browsers, allowing for copy-pasting and even text search of the numerals. This digital revival makes a unique, thousand-year-old notation system accessible and functional for modern typing and display.

Why It Matters

It digitally preserves a historical notation, blending ancient math with modern typography.
