Frequently Asked Questions

Why use ASCII / Unicode flowcharts instead of Mermaid or PNG images?

ASCII diagrams require no JavaScript rendering engine, load with zero latency, and render identically inside raw terminal pagers, git diffs, and plain text viewers.

Are Unicode box-drawing characters supported on all operating systems?

Yes! Modern monospace terminal fonts (JetBrains Mono, Fira Code, Menlo, Consolas) on macOS, Windows, and Linux have built-in support for standard box drawing glyphs.
