The typographic closing double quotation mark and the neutral double quotation mark are similar to and sometimes stand in for the ditto mark and the double prime symbol. Likewise, the typographic opening single quotation mark is sometimes used to represent the ʻokina while either the typographic closing single quotation mark or the neutral single quotation mark may represent the prime symbol. Characters with different meanings are typically given different visual appearance in typefaces that recognize these distinctions, and they each have different Unicode code points. Despite being semantically different, the typographic closing single quotation mark and the typographic apostrophe have the same visual appearance and code point (U+2019), as do the neutral single quote and typewriter apostrophe (U+0027). (Despite the different code points, the curved and straight versions are sometimes considered multiple glyphs of the same character.)
