Devanagari Text Engine for Unity

Unified Hindi, Marathi & Kruti Dev text rendering for Unity.

Solves broken conjuncts (क्ष, त्र), detached matras, and missing ligatures in Unity's text components. Supports Unicode and Legacy (Kruti Dev) workflows with full mixed-language text support.

Features

• ✅ Unicode NFC Normalization — fixes broken conjuncts for Hindi & Marathi
• ✅ Legacy Mode (Kruti Dev) — auto-converts Unicode to Kruti Dev encoding on the fly
• ✅ Mixed-Language Safe — English, numbers, and symbols (₹, etc.) pass through unchanged in Legacy Mode
• ✅ Marathi Support — proper ळ (LLA) and ऱ (Eyelash Ra) handling
• ✅ Input Fields — real-time conversion while typing (TMP & Legacy)
• ✅ Devanagari Numerals — toggle between Western (0-9) and Devanagari (०-९)
• ✅ TextMeshPro & Legacy Text — works with both UI systems
• ✅ Zero-Config — attach component, assign font, done
• ✅ Editor Tools — font validator, demo scenes, easy testing
• ✅ Bundled Assets — includes KrutiDev010.ttf and pre-built TMP SDF asset

Quick Start

Legacy Mode (Recommended — Kruti Dev Font)

1. Add Devanagari Text Fixer (or Devanagari Text Mesh Pro) to your GameObject.
2. Assign the included KrutiDev010_SDF font asset to your TMP component.
3. Done! Legacy Mode is on by default — Hindi/Marathi text renders correctly out of the box.

Mixed text works too: A string like "Hello नमस्ते ₹999 बाळ" will convert only the Devanagari portions, leaving English and symbols untouched.

Unicode Mode (Noto Sans / Google Fonts)

1. Uncheck Legacy Mode in the Inspector.
2. Select Hindi or Marathi (important for ळ / ऱ handling).
3. Assign a Unicode-compliant Devanagari font.

Input Fields

1. Create a TMP Input Field.
2. Add the Devanagari TMP Input Field component.
3. Assign KrutiDev010_SDF to the Input Field's Text Component.
4. Play — text converts and shapes in real-time as you type. Placeholder text is supported.

Components

Component	Description
DevanagariTextFixer	Universal fixer. Attach to any Text/TMP object.

Programmatic Usage
