# Unicode Evidence Offset Mapping

Build-time release reference. Runtime readiness, deployment, payment settlement and external indexing are not evaluated here. Prices are proposed; this file cannot authorize execution or payment.

Translate caller-supplied UTF-8 byte, UTF-16 code-unit or Unicode code-point offsets into all three coordinate systems and LF-based line/column positions. Only exact scalar boundaries are valid; text is never normalized or rewritten.

Release: 0.29.0. Built: 2026-10-06T15:38:00Z.

## Choose for
- Reconcile byte and character offsets from different extraction tools
- Convert annotation spans between UTF-8 UTF-16 and code-point systems

## Outside this profile
- Grapheme cluster, display-width, tokenizer or normalization mapping
- Offsets into binary files or malformed Unicode

Proposed nominal USD 0.003 per successful call; payer fees excluded. No verified runtime availability.
