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.
Arabic completely unreadable
Letters disconnected, RTL ignored, words reversed. Native speakers cannot read the text at all. No emoji support out of the box.
Arabic letters connect, but BiDi is broken
The plugin handles basic Arabic shaping — letters connect into words correctly. But there's no real BiDi algorithm. With embedded numbers, English words, or punctuation (chat, dialogue, prices, dates) the visual order is wrong — native readers struggle. On some inputs the plugin doesn't activate at all and falls back to the exact same broken output as TextMeshPro. Emoji don't work either way.
Everything works correctly
Full Unicode BiDi algorithm. Mixed scripts in correct order. Color emoji including complex ZWJ sequences. Production-ready out of the box.
Real Unity Editor screenshots — same text, same font, same scene
Built for Real Game Scenarios
If any of these sound familiar, UniText is your solution.
Dialogue Systems
Rich text with bold, italic, colors — in any language. Arabic dialogues read right-to-left. Hindi vowels connect properly. Emoji reactions just work.
Game Localization
Localizing to Arabic, Hebrew, Hindi, Thai, or Bengali? UniText is the only Unity text solution that renders these scripts correctly.
3D Floating Text
Damage numbers, name plates, world signs — rendered via MeshRenderer. No Canvas overhead. Full Unicode support in 3D space.
Player-Generated Content
Chat messages, player names, custom text — any Unicode input, including complex emoji sequences, rendered correctly.
Performance-Critical Games
Mobile, VR, large worlds — zero garbage collection means no stuttering, even with hundreds of text objects.
Rich Text & Markdown
Use familiar **bold**, *italic*, ~~strikethrough~~ syntax directly in Unity. Perfect for dialogue systems, tutorials, and in-game text.
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.
Custom modifier creation in 10 lines of C#
Modular Architecture
Plug & play modifier system. Add only what you need. Create custom text effects in minutes with a simple C# API.
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.
