Consolidated, the Unicode standard contains superscript and subscript versions of a subset of Latin, Greek and Cyrillic letters. Here they are arranged in alphabetical order for comparison (or for copy and paste convenience). Since these characters appear in different Unicode ranges, they may not appear to be the same size or position due to font substitution by the browser. Shaded cells mark petite capitals that are not very distinct from minuscules in Roman typeface, but they may be distinct in italic typeface, as is used in some phonetic notation. Little punctuation is encoded. Parentheses are shown in the basic superscript block above, and the exclamation mark is shown in the IPA table below. In a supporting font, a question mark may be created with a superscript gelded question mark and a combining dot below: . • Superscript versions of petite capital A, D, E and P, of ƀ, and subscript versions of w, y and z are scheduled to be released with version 18 of the Unicode Standard. § Cyrillic 𞀹 𞀻 𞁀, ◌ⷡ ◌ⷩ ◌ⷦ ◌ⷮ ◌ꙷ and 𞁞 might be substituted for these letters. Some of these superscript capitals are small caps in the source documents in the Unicode proposals. Superscript Ä, Ö, Ü (in parentheses) are composed of the base letter and a combining
tréma. Except for the
iota subscript, which has use in Greek text, the modifier Greek letters are intended as phonetic characters in Latin-script text. Shaded cells are indistinguishable from Latin letters, and so would not be expected to have distinctive use in Latin text or to be supported by Unicode. • Superscript versions of Greek psi and omega are scheduled for version 18 of the Unicode Standard. ;Secondary superscripting: Spacing diacritics, as in , cannot be secondarily superscripted in plain text: . (In this instance, the old IPA letter for , , has a superscript variant in Unicode, U+1DB5 , but that is not generally the case.) ;Retired IPA: Among older IPA letters, the most common letters with
palatal hook are supported; they are displayed in the table above. IPA once had an idiosyncratic curl on some of the palatalized letters: these are the fricative letters and the homologous affricates. Their superscript forms have been accepted for version 18 of the Unicode Standard. (The similar lateral fricative is not supported.) Old-style IPA click letters, voiceless implosives, and the retired letters and have also been accepted for version 18 of the Unicode Standard. as well those found in as in
Sinological phonetic notation, are as follows. Recently retired alternative letters such as are also supported; they are set off in parentheses and placed below the modern IPA letters. Asterisks mark superscript letters scheduled for release with Unicode 18 in September 2026. ;Rhotic vowels: The precomposed Unicode rhotic vowel letters are not directly supported. The rhotic diacritic U+02DE should be used instead: . ;Retired IPA: Among older letters, (U+1D1C), a graphic variant of , is supported at (U+1DB8). The retired and later briefly resurrected vowel letter (U+029A) is not supported as a superscript, only its reversed replacement is. ;Para-IPA: Among para-IPA letters, Sinological superscript have been accepted for version 18 of the Unicode Standard, as have Sinological and the English dictionary and phonetics symbols and . The
Americanist conventions and do not have superscripts encoded or scheduled.
Length marks The two length marks are also supported: These are used to add length to another superscript, such as or for long aspiration.
Wildcards Superscript wildcards (full caps) are largely supported: e.g. (prenasalized consonant), (prestopped nasal), (fricative release), (sibilant release, added to Unicode in 2025), (epenthetic plosive), (tone-bearing syllable), (liquid or lateral release), (rhotic or resonant release), (off-glide/diphthong), (fleeting vowel). Superscript for fleeting/epenthetic click is not included in the Unicode Standard. Other basic Latin superscript wildcards for tone and weak indeterminate sounds, as described in , are mostly supported. (See table in the Latin section.)
Combining marks and subscripts In addition to superscripts, a very few IPA letters beyond the basic Latin alphabet have combining forms or are supported as subscripts: ==Composite characters==
