Corresponds historically to U+093E DEVANAGARI VOWEL SIGN AA. The character descends from the Brahmi vowel length marker, which is just discernible as the difference between U+0E34 SARA I and U+0E35 SARA II and between U+0E38 SARA U and U+0E39 SARA UU. This character is also known as lak khang in Thai, and a long variant form is encoded separately as U+0E45 LAKKHANGYAO, the length marker used with U+0E24 THAI CHARACTER RU and U+0E26 THAI CHARACTER LU.

It is probably of different origin in the combination U+0E40 SARA E ... U+0E32, which appears to correspond to U+094B DEVANAGARI VOWEL SIGN O, the combination U+094E DEVANAGARI VOWEL SIGN PRISHTHAMATRA E, U+093E, and the multipart vowels U+0BCB TAMIL VOWEL SIGN OO and U+17C4 KHMER SIGN OO. The vowel signs for AU have an extra element in these scripts, which is represented as the additional vowel symbol U+0EBB LAO VOWEL SIGN MAI KON in the Lao script and as U+1A62 TAI THAM VOWEL SIGN MAI SAT. ThaI has lost this extra element, which appears to derive from the Brahmi vowel length marker.
