Latin Extended-F is a Unicode block containing modifier letters, nearly all IPA and extIPA, for phonetic transcription. The Latin Extended-F and -G blocks contain the first Latin characters defined outside of the Basic Multilingual Plane (BMP). They were added to the free Gentium Plus and Andika fonts with version 6.2 in February 2023. Some computers have, and supported on the font Calibri.
In 2020, the International Phonetic Association endorsed the encoding of superscript IPA letters in a proposal to the Unicode Commission for broader coverage of the IPA alphabet. The proposal covered all IPA letters that were not yet supported (apart from the tone letters), including the implicit retroflex letters (IPA|ꞎ ᶑ  ), as well as the two length marks (IPA|ː ˑ) and old-style affricate ligatures.[3] [4] [5] A separate request by the International Clinical Phonetics and Linguistics Association for an expansion of extIPA coverage endorsed superscript variants of all extIPA fricative letters, specifically for the fricative release of consonants.[6]
U+10786 and U+107B1 were proposed for superscript ꞵ and ꭓ (that is, for Latin variants of, used in IPA to denote roundedness, and) but have not been assigned.[7] [8]
