UniText

🚀 UniText 2.0 — Coming Soon. The biggest update since the initial release — rewritten from scratch.

See what's new in 2.0

🎨 No more materials. UniTextAppearance is gone. Effects are configured directly on components and can target individual parts of the text.

🔤 Variable Fonts. Full axis support — weight, width, italic, slant, optical size — controllable per-character. Three-tier resolution: variable axes → static faces → synthesis. Same algorithm as CSS. No other game engine has this (except Godot).

⚡ SDF & MSDF rendering from raw curves. Runtime Bézier rasterization via Burst. No pre-baked atlases. A single global Texture2DArray: 1 draw call instead of N, automatic LRU eviction, adaptive tile sizes by glyph complexity, defragmentation.

👨‍👩‍👧‍👦 Font Families. Primary + faces (bold, italic, light). CSS §5.2 weight matching — same algorithm browsers use. Redesigned UniTextFontStack.

🌍 UniTextWorld. 3D text without Canvas. Full pipeline (Unicode, BiDi, shaping, effects, emoji, fallback) via MeshRenderer.

✨ Effects. Outline and shadow with per-character control. Multi-pass rendering. Works in Canvas and World.

🔠 SmallCaps. Native OpenType smcp via HarfBuzz. Proper glyphs when available, automatic synthesis when not.

🇹🇭 Thai & Lao word segmentation. Dictionary-based word breaking (26K Thai words). Correct line breaks for SE Asian scripts.

📦 Zstd font compression. ~2.7x smaller builds for Latin/Arabic, ~1.3x for CJK. ~600 MB/s desktop, ~175 MB/s mobile.

📝 Markdown. **bold**, *italic*, ~~strikethrough~~, ++underline++ — out of the box.

🛠️ Editor UX. Style selector with ~30 presets and search. Font family inspector. Glyph picker with live preview. Atlas preview tabs. Styles & Style Presets.

🐛 ...and a mountain of fixes. Full changelog and migration notes included with the release.

⚠️ Major version bump — expect breaking changes from 1.x.

---

Industrial-grade Unicode 17.0 text engine for Unity. Built on HarfBuzz — the same shaping engine used by Chrome, Firefox, Adobe InDesign, and Android.

Passes all 891,757 official Unicode conformance tests. Zero GC allocations at runtime. 3-21x faster than TextMeshPro.

✨ Key Features

• 🌐 150+ languages — Arabic, Hebrew, Hindi, Thai, CJK, and every other Unicode script. One component, automatic font fallback
• 🔄 Full BiDi — mixed LTR/RTL with numbers and punctuation renders correctly (UAX #9)
• 😀 Native color emoji — ZWJ sequences, skin tones, flags via system fonts. Zero extra build size

• 🏷️ Extensible markup — 15+ built-in modifiers, custom parse rules, shared configurations
• 👆 Interactive text — clickable/hoverable regions with typed events and highlight system
• 🚀 Zero allocations — custom pooling, parallel processing, 3-21x faster than TextMeshPro
