UniText Free (Raw Text Engine Core)

UniText Folio — Every language. Any style. No fonts required. Top performance.

UniText supplies a common text model for labels, input fields, rich editors and virtualized documents in Canvas UI and world space. Capabilities include native emoji, variable and pixel fonts, Font Memory Mapping, rich editing, layered styles and text animation. Modifier, parser, input and decoration extensions compose through the same pipeline. Shared LightSide systems provide reusable infrastructure for authoring and runtime work.

UniText belongs to the wider LightSide ecosystem. Common implementations include paints, gradients, textures, filters, state, clocks, input, geometry, GPU infrastructure and editor tools. Text, shapes and Lottie use shared shaders, materials and batching. MoveIt animates exposed component and nested layer properties.

_{Also available on the Unity Asset Store.}
