[1] FUT differs from the International Phonetic Alphabet (IPA) notation in several ways, notably in exploiting italics or boldface rather than using brackets to delimit text, in the use of small capitals for devoicing, and in more frequent use of diacritics to differentiate places of articulation.
The basic FUT characters are based on the Finnish alphabet where possible, with extensions taken from Cyrillic and Greek orthographies.
Other sources have ᴃ and ᴆ for fricative ʙ ᴅ, and ᴩ ρ for the uvular trills.
The Uralic languages transcribed with this system do not contain non-pulmonic consonants except paralinguistically, thus only clicks are supported by FUT.
There are two conventions: a leftward arrow, for p˿ b˿ t˿ d˿ ḱ˿ ǵ˿ etc., and Greek letters, for ᴨ π ᴛ τ ᴋ κ etc.
[5] For phonetic transcription, numerous small differences from IPA come into relevance: Examples: The IETF language tags register fonupa as a subtag for text in this notation.
Support is available through any good phonetics font, such as (among free fonts) Gentium, Andika, Noto, DejaVu and EB Garamond, though lower-case and small-capital ᴄ, л, o, v, w and z may not be distinct in italic typeface and are rarely distinct in bold.
