U+0274 Latin Letter Small Capital N

The Wikipedia has the following information about this codepoint:

The voiced uvular nasal is a type of consonantal sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ⟨ɴ⟩, a small capital version of the Latin letter n; the equivalent X-SAMPA symbol is N.

The uvular nasal is a rare sound cross-linguistically, occurring as a phoneme in only a small handful of languages. It is complex in terms of articulation, and also highly marked, as it is inherently difficult to produce a nasal articulation at the uvular point of contact. This difficulty can be said to account for the marked rarity of this sound among the world's languages.

The uvular nasal most commonly occurs as a conditioned allophone of other sounds, for example as an allophone of /n/ before a uvular plosive as in Quechua, or as an allophone of /q/ before another nasal consonant as in Selkup. However, it has been reported to exist as an independent phoneme in a small number of languages. Examples include the Klallam language, Tagalog language, the Tawellemmet and Ayr varieties of Tuareg Berber, the Rangakha dialect of Khams Tibetan, at least two dialects of the Bai language, the Papuan language Mapos Buang, and the Chamdo languages: Lamo (Kyilwa dialect), Larong sMar (Tangre Chaya dialect), Drag-yab sMar (Razi dialect). In Mapos Buang and in the Bai dialects, it contrasts phonemically with a velar nasal. In the Chamdo languages it contrasts phonemically with /ŋ/, /ŋ̊/, and /ɴ̥/. The syllable-final nasal in Japanese was traditionally said to be realized as a uvular nasal when utterance-final, but empirical studies have disputed this claim.

There is also the pre-uvular nasal in some languages such as Yanyuwa, which is articulated slightly more front compared with the place of articulation of the prototypical uvular nasal, though not as front as the prototypical velar nasal. The International Phonetic Alphabet does not have a separate symbol for that sound, though it can be transcribed as ⟨ɴ̟⟩ (advanced ⟨ɴ⟩), ⟨ŋ̠⟩ or ⟨ŋ˗⟩ (both symbols denote a retracted ⟨ŋ⟩). The equivalent X-SAMPA symbols are N\_+ and N_-, respectively.
