The Wikipedia has the following information about this codepoint:

The Uralic Phonetic Alphabet (UPA) or Finno-Ugric transcription system is a phonetic transcription or notational system used predominantly for the transcription and reconstruction of Uralic languages. It was first published in 1901 by Eemil Nestor Setälä, a Finnish linguist.
UPA differs from the International Phonetic Alphabet (IPA) notation in several ways.
The basic UPA characters are based on the Finnish alphabet where possible, with extensions taken from Cyrillic and Greek orthographies. Small-capital letters and some novel diacritics are also used.
