Industrial-grade Unicode 17.0 text engine with HarfBuzz shaping. 150+ languages, full BiDi, native color emoji, extensible markup. Zero-allocation, 3-21× faster than TextMeshPro.Text engine for Unity that correctly renders every writing system - Arabic, Hebrew, Hindi, Thai, CJK, emoji, and 150+ others. Built on HarfBuzz, the same shaping engine used by Chrome, Firefox, Adobe InDesign, and Android.Passes all 861,948 official Unicode 17.0 conformance tests. Zero GC allocations at runtime. 3-21× faster than TextMeshPro.Add the component, type any language — it works. No plugins, no configuration, no workarounds.What it handlesComplex scripts — Arabic ligatures, Hebrew BiDi, Hindi conjuncts, Thai word breakingBidirectional text — mixed LTR/RTL with numbers and punctuation renders correctlyColor emoji — ZWJ sequences (👨👩👧👦), skin tones, flags via system fonts.
