The Wikipedia has the following information about this codepoint:

The apostrophe ( ’ or ' ) is a punctuation mark, and sometimes a diacritical mark, in languages that use the Latin alphabet or certain other alphabets. In English, it serves three purposes:

  • The marking of the omission of one or more letters (as in the contraction of do not to don't).
  • The marking of possessive case (as in the eagle's feathers, or in one month's time).
  • The marking by some as plural of written items that are not words established in English orthography (as in P's and Q's).

Apostrophe comes ultimately from Greek ἡ ἀπόστροφος [προσῳδία] (hē apóstrophos [prosōidía], "[the accent of] 'turning away', or elision"), through Latin and French.

The apostrophe looks the same as a closing single quotation mark, although they have different meanings. The apostrophe also looks similar to, but is not the same as, the prime symbol ( ′ ), which is used to indicate measurement in feet or arcminutes, as well as for various mathematical purposes, and the ʻokina ( ʻ ), which represents a glottal stop in Polynesian languages. Such incorrect substitutes as ´ (acute) and ` (grave) are common in unprofessional texts, where an ambiguous treatment of the apostrophe in digital typesetting (as explained below) is a major factor of this confusion.
