ISO 15919

From Wikipedia, the free encyclopedia

ISO 15919 (2001) is an international standard for the transliteration of Indic scripts to the Latin alphabet. It uses diacritics to map the much larger set of Brahmic consonants and vowels to the Latin script. See also Transliteration of Indic scripts: how to use ISO 15919. The Devanagari-specific portion is nearly identical to the academic standard, IAST: "International Alphabet of Sanskrit Transliteration", and to the United States Library of Congress standard, ALA-LC: [1]

[edit] Comparison with IAST

For the most part, IAST and ISO 15919 are identical. The following changes were made to accommodate an extended repertoire of Devanagari characters that correspond to other Indic scripts:

Devanagari	IAST	ISO 15919	Comment
ए/े	e	ē	To distinguish between long and short 'e' in some Indic scripts. 'E' now represents ऎ/ॆ.
ओ/ो	o	ō	To distinguish between long and short 'o' in some Indic scripts. 'O' now represents ऒ/ॊ.
ं	ṃ	ṁ	In ISO 15919, ṃ is used to specifically represent Gurmukhi Tippi ੰ.
ऋ/ृ	ṛ	r̥	In ISO 15919, ṛ is used to represent ड़.
ॠ/ॄ	ṝ	r̥̄	For consistency with r̥
