First & Only
Text Engine for Unity
Every language. Every emoji. Every style. Production-grade, extensible, high-performance, built on industry standards.
Unicode 17.0 · HarfBuzz · SDF/MSDF · Variable Fonts · Zero GC
1.8 Billion Users Left Behind
If your game has Arabic, Hebrew, Hindi, Thai, or Bengali-speaking players — TextMeshPro is showing them broken text. These aren't edge cases — they're a quarter of the world's population.
Everything You Need
Built on the same technologies used by Chrome, Firefox, Adobe, and Android.
Every Writing System
Every script on Earth — tested and passed. 891,757 official Unicode conformance tests, zero failures. From Arabic to Tibetan.
Variable Fonts
One font file, infinite variations. Smoothly animate weight, width, slant — in real time. One font replaces your entire font family.
100 UniText + 100 TextMeshPro instances animating Font Size simultaneously. They're stacked at the same position, so all 200 look like a single block.
Multi-Core Processing
Text layout runs across all CPU cores. 100, 500, 1000 text objects — performance scales linearly.
Full Color Emoji
Families 👨👩👧👦, flags 🇬🇪, skin tones 👋🏻👋🏿 — all correct. Uses device fonts: zero impact on build size, always up-to-date.
Outline & Shadow
Rich text effects via simple tags. Customizable color, thickness, offset, and softness — all GPU-accelerated.
3D World Text
Text in 3D space via MeshRenderer — no Canvas required. Full feature parity: every language, every emoji, every effect — in world space.
No other Unity text solution ships CJK this way.
CJK Without Font Files
Chinese, Japanese and Korean come straight from the OS — no font assets, no baked atlas. Memory-mapped: only the glyphs you use reach RAM.
Smart Word Breaking
Thai, Lao, and other SE Asian scripts don't use spaces between words. UniText knows where to break lines — correctly, every time.
100% Unicode Conformance
We pass every single official Unicode test. No exceptions.
Benchmark Comparison
Real benchmarks on Android production build.
Speed Comparison
Memory & GC
* 100 objects, 10 iterations, 3 warmup, ~2300 characters per object (Latin + Arabic + Hebrew + Mixed). UniText.UseParallel = false.
Glyph Rendering
Adding glyphs to texture atlas
Smaller Builds and Bundles
Font compression keeps your shipped game tiny
Sub-millisecond decompression at runtime — players won't notice.
Engineered at a different scale
The codebase tells the story — UniText is a complete text engine, not a component.
Far more engine — and still faster and leaner than TMP.
All Platforms Supported
Native HarfBuzz and FreeType libraries compiled for every major platform and architecture.

- 1.TMP has no native BiDi/Arabic/Hebrew. The usual plugin (RTL Text Mesh Pro) is a workaround, not real RTL: no proper Unicode Bidirectional Algorithm (UAX #9) — a heuristic glyph "fixer" whose own docs note mixed English/RTL multiline text breaks — and Arabic-script shaping via a fixed presentation-form table only (no OpenType shaping, no other complex scripts).
- 2.UI Toolkit: requires the Advanced Text Generator (HarfBuzz/ICU) — opt-in in Unity 6.4, default from 6.5. Without ATG there is no shaping/BiDi/ICU.
- 3.TMP does not compose ZWJ/skin-tone/flag sequences at all; UI Toolkit attempts them but Unity itself flags emoji with flags and skin tones as "problematic".
- 4.TMP has no bundled UCD table: emoji data tracks Unicode 14.0, character properties come from the .NET runtime.
- 5.UI Toolkit text-generation parallelization ships in Unity 6.5.
- 6.No engine builds true extruded 3D geometry. UniText stacks offset quad copies (2.5D, z=0) with a near→far gradient and a bevel mode; TMP uses a faux bevel via normal-map shading.
- 7.TMP fixed-ratio distribution (wordWrappingRatios 0.4) forces ~40% of the slack into inter-letter spacing on every script (not script-aware), hardcodes last-line alignment (no text-align-last), and tolerates 5% box overflow.
- 8.UniText merges all UniTextWorld components sharing a material and sorting into one mesh → typically a single draw call per group (extra meshes only past the ~64k-vertex limit). World-space TextMeshPro renders each object as its own MeshRenderer with no cross-object batching, so draw calls grow linearly with the number of text objects.
- 9.UniText direct developer support: responses within 10 minutes, bug fixes from 1 hour to 1 day, feature implementation from 3 hours to 3 days. TMP and UI Toolkit only have Unity’s official issue tracker and community forums, with no guaranteed response or fix times.

- 1.TMP has no native BiDi/Arabic. RTL editing needs a third-party plugin (RTL Text Mesh Pro) — a heuristic glyph "fixer", not real RTL: no proper Unicode Bidirectional Algorithm (UAX #9), only fixed Arabic-script presentation forms (no OpenType shaping), with known mixed-direction multiline issues.
- 2.UI Toolkit RTL/complex-script editing requires the Advanced Text Generator (opt-in in Unity 6.4, default from 6.5).
- 3.UI Toolkit’s runtime TextField has no undo/redo (the handler’s UndoRedoPerformed is an unimplemented TODO); editor IMGUI fields are a separate path.
- 4.TMP’s "Allow Rich Text Editing" edits the raw markup string (tags preserved) — there is no command to toggle bold/italic/color over a selection.
- 5.Both TMP and UI Toolkit copy/paste plain text only via Unity’s systemCopyBuffer — no HTML/Markdown/RTF or images.
- 6.UI Toolkit’s cut/copy/paste context menu is wired only in the Editor (EditorContextualMenuManager); a built player has no built-in text context menu.
