The International Alphabet of Sanskrit Transliteration (IAST) is a transliteration scheme that allows the lossless romanisation of Indic scripts. The scheme’s intention is to eliminate ambiguity.
The IAST standard deviates from the ISO 15919 standard as follows:
| IAST | ISO 15919 |
|---|---|
| e | ē |
| o | ō |
| ṃ | ṁ |
| ṛ | r̥ |
| ṝ | r̥̄ |
| ḷ | l̥ |
| ḹ | l̥̄ |
