Modifier letter apostrophe

In the International Phonetic Alphabet, it is used to express ejective consonants, such as / kʼ /, / tʼ /, etc.

The modifier letter apostrophe (ʼ) is a glyph.

It denotes a glottal stop (IPA /ʔ/) in orthographies of many languages, such as Nenets and the artificial Klingon language.

It is encoded at U+02BC ʼ MODIFIER LETTER APOSTROPHE (HTML ʼ).

In Unicode code charts it looks identical to the U+2019 ’ RIGHT SINGLE QUOTATION MARK,[1] but that is not true for all fonts, and (unlike the U+2019, which has the "Punctuation, Final quote" (Pf) General Category) it has the "Letter, modifier" (Lm) General Category.

Although the Unicode standard versions 1.0[2]–2.1.9[3] considered this character as the "preferred character for a punctuation apostrophe", versions since 3.0.0,[4] including the current one,[5] consider the U+2019 ’ RIGHT SINGLE QUOTATION MARK as the preferred character. There are reasoned objections to this decision, such as that in English, an apostrophe is a part of a word.[6]

As of Version 4.4, Android browsers render U+02BC as a combining diacritic when it is followed by a letter, superimposing it above that letter.

U+02BC ʼ MODIFIER LETTER APOSTROPHE plays the role of Ukrainian apostrophe in internationalized domain names.[7]
