All 22 Scripts + Emoji
The flagship stress test. One buildDocumentPDFBytes() call, every Unicode script pdfnative supports — 22 writing systems with full BiDi reordering and OpenType GSUB/GPOS shaping — plus native COLRv1 colour emoji, composed into a single PDF entirely in your browser. The text-routing engine inspects every code point and dispatches it to the right embedded font automatically, so a single paragraph can freely mix Arabic, Tamil, Japanese and emoji.
Heads-up: this preset embeds up to 24 fonts (22 scripts + Latin + colour emoji). The first run fetches several megabytes of font data from the CDN — give it a few seconds. Everything after that is instant.

The 22 scripts at a glance
Every writing system below ships as a bundled Noto font module and renders through the same shaping engine. The demo reads this table directly — what you see here is what lands in the PDF.

What this exercises:
- Automatic per-code-point font routing — one mixed paragraph is split into runs and each run dispatched to its embedded CIDFont; Latin stays on Helvetica/Noto Sans.
- BiDi (UAX #9) — Arabic, Hebrew, and Ethiopic runs are reordered right-to-left and correctly interleaved with left-to-right neighbours and digits.
- OpenType shaping — GSUB ligatures/conjuncts and GPOS mark positioning for the Indic, Thai, Khmer, Myanmar, Tibetan and Sinhala runs; Arabic joining forms.
- COLRv1 colour emoji — Noto Color Emoji layers rendered as native PDF vector fills (no rasterization), or monochrome via Noto Emoji.
- Subsetting — each of the 22+ fonts is subset to only the glyphs used, then embedded as a CIDFont Type2 with Identity-H.
