These are the letters of the Hindi Alphabet. Yes, these are NOT a "font" of the Devanagari scipt, they are actual vector sprites. There are 11 vowels + 4 extras, specifically: अ, आ, इ, ई, उ, ऊ, ऋ, ए, ऐ ,ओ, औ, अं, अः, अँ, ॲ (a, ā, i, ī, u, ū, ṛ, e, ai, o, au, aṅ, aḥ, ãṃ, æ, respectively) and there are 33 consonants + 2 extras: क, ख, ग, घ, ङ, च, छ, ज, झ, ञ, ट, ठ, ड, ढ, ण, त, थ, द, ध, न, प, फ, ब, भ, म, य, र, ल, व, श, ष, स, ह, क्ष, त्र, ज्ञ, ड़, ढ़ (ka, kha, ga, gha, ṅa, ca, cha, ja, jha, ña, ṭa, ṭha, ḍa, ḍha, ṇa, ta, tha, da, dha, na, pa, pha, ba, bha, ma, ya, ra, la, va, śa, ṣa, sa, ha, kśa, tra, gya, ṛa, ṛha, respectively)
Note that some of them, specially ॲ and अँ dont officialy belong to the actual varnamala (alphabet) and are just diacritics, most common examples of diacritics with short a or अ is अं and अः, which is claimed to be in the varnamala. Other consonants like क्ष त्र and ज्ञ are saṅyojans, meaning they are already made up of more than one varna (letter) like त् + र् + अ = त्र, क् + श् + अ = क्ष, ज् + ञ् + अ = ज्ञ
