It represents the vowel sound "ai" and is placed above the consonant glyph it modifies, serving as an independent vowel modifier distinct from inherent vowels in the script. This character is part of the Tirhuta block, encoded in Unicode version 7.0 in 2014, and supports the accurate digital representation and preservation of Maithili literature and inscriptions, aiding in the revival and modern use of this endangered script.
