Wikipedia Wrote:Many earlier (pre 1985) computer displays and printers rendered the ASCII apostrophe as a typographic apostrophe, and rendered the ASCII grave accent ( ` ) U+0060 as a matching left single quotation mark. This allowed a more typographic appearance of text: ``I can't'' would appear as ‘‘I can’t’’ on these systems. This can still be seen in many documents prepared at that time.
