Modifier letter apostrophe

In Unicode code charts it looks identical to the U+2019 ’ RIGHT SINGLE QUOTATION MARK,[1] but this is not true for all fonts.

In early Unicode (versions 1.0[2]–2.1.9[3]) U+02BC was preferred for the punctuation apostrophe in English.

In the International Phonetic Alphabet, it is used to express ejective consonants, such as [kʼ] and [tʼ].

In one version of the Kildin Sami alphabet, it denotes preaspiration.

[6] In the Ukrainian alphabet and in the Belarusian alphabet, U+02BC is used for the semi-letter 'apostrophe' (which plays a role similar to Russian ⟨ъ⟩) in certain contexts, such as, for example, in internationalized domain names where a punctuation mark would be disallowed.
