Modifier letter apostrophe
The letter apostrophe is encoded at U+02BC ʼ MODIFIER LETTER APOSTROPHE (HTML
In Unicode code charts it looks identical to the U+2019 ’ RIGHT SINGLE QUOTATION MARK, but this is not true for all fonts. The primary difference between the letter apostrophe and U+2019 is that the letter apostrophe U+02BC has the Unicode General Category "Letter, modifier" (Lm), while U+2019 has the category "Punctuation, Final quote" (Pf).
In early Unicode (versions 1.0–2.1.9) U+02BC was preferred for the punctuation apostrophe in English. Since version 3.0.0, however, U+2019 is preferred, because it is defined as a punctuation mark. The behavior of Unicode letters and punctuation marks differs, causing complications if punctuation code points are used for letters or vice versa.
In the Ukrainian alphabet, U+02BC is used for the semi-letter 'apostrophe', which plays a role similar to Russian ⟨ъ⟩, for example in internationalized domain names where a punctuation mark would be disallowed.
