Unicode 11.0 just added another Devanagari letter AY (standalone is U+A8FE DEVANAGARI LETTER AY, combining mark is U+A8FF DEVANAGARI VOWEL SIGN AY) per https://www.unicode.org/L2/L2015/15335-devanagari-ay.pdf Should this letter be added to this template and if so, where?

FYI: Ten new Devanagari Unicode characters have been created with Unicode version 15.0. They are described as "auspicious signs from Indian inscriptions and manuscripts from the 11th century onward" per Devanagari Extended-A.
