Box Drawing

Pixel-perfect rendering of Unicode box-drawing, block, Braille, and Powerline glyphs — drawn analytically rather than rasterized from a font.

---

Unlike most terminals, Otty treats arrows (← → ↑ ↓) and triangles (◀ ▶ ▲ ▼) as part of box-drawing: when one sits next to a connecting line, its stem extends to meet the rule instead of leaving a gap — so flow diagrams and arrows render seamlessly.
