ISO 11940:1998 PDF

Overview

ISO 11940:1998 - "Information and documentation - Transliteration of Thai" defines a strict, completely reversible system for converting Thai script into Roman characters. Its purpose is machine‑readable, unambiguous Romanization (transliteration) that allows automatic transmission and exact reconstitution of Thai text by people or systems. The standard prioritizes reversibility over phonetic fidelity and uses diacritics, digraphs and ordering rules to represent Thai characters uniquely.
