• Lossless round-trip envelope with integrity verification
• NFC / NFD and combining-mark preservation

• Shared cross-runtime verification corpus

Exact source recovery

The exact-recovery mode preserves the original Latin source, including:

• case
• NFC versus NFD representation
• precomposed versus decomposed forms
• alias choice
• combining-mark order
• punctuation
• whitespace
• supplementary Unicode characters

This allows metadata-backed round trips to recover the exact original source key even where visible transliteration mappings are intentionally many-to-one.

Supported scripts / systems

• Devanagari
• Gujarati
• IAST
• ISO 15919 core profile
• Extended Indic
• Hunterian
• Plain English
• Vedic accent marks

Runtime support

• Dart: 3.4+
• Python: 3.12+
• JavaScript / Node.js: Node.js 20+ / ES2023+
• PHP: 8.3+

Verification

The four implementations are maintained against the same transliteration behavior and verification corpus.

Verified areas include:

• Latin / IAST → Devanagari
• Latin / IAST → Gujarati
• Devanagari → canonical IAST
• Gujarati → canonical IAST
• Devanagari ↔ Gujarati
• Plain English / Hunterian transcription
• exact metadata-backed round trips
• NFC / NFD handling
• combining-mark edge cases
• Vedic fixtures

The current shared corpus contains 497 transliteration cases plus 22 Vedic fixtures.

Repository model

This repository is the canonical source repository for all four implementations.

The PHP package is additionally published from a generated PHP-only mirror repository so that composer.json is available at the repository root for Packagist. Development remains centralized in this canonical repository.
