The Wikipedia has the following information about this codepoint:
Ṇa (also romanized as Nna) is a consonant of Indic abugidas. In modern Indic scripts, Ṇa is derived from the early "Ashoka" Brahmi letter after having gone through the Gupta letter . As with the other cerebral consonants, ṇa is not found in most scripts for Tai, Sino-Tibetan, and other non-Indic languages, except for a few scripts, which retain these letters for transcribing Sanskrit religious terms.
