single quote
     
         "'" {ASCII} character 39.
     
        Common names include single quote; quote; {ITU-T}: apostrophe.
        Rare: prime; glitch; tick; irk; pop; {INTERCAL}: spark;
        {ITU-T}: closing single quotation mark; {ITU-T}: acute accent.
     
        Single quote is used in {C} and derived languages to introduce
        a single character {literal value} which is represented
        internally by its ASCII code.  In the {Unix} {shells} and
        {Perl} single quote is used to delimit strings in which
        variable substitution is not performed (in contrast to
        {double-quote}-delimited strings).
     
        Single quote is often used in text for both open and close
        single quotation mark and apostrophe.  Typesetters use two
        different symbols - open has a tail going up, close and
        apostrophe have tails hanging down (like a raised {comma}).
        Some people use {back quote} (`) for open single quotation
        mark.
