apostrophe character

基本解释

Two sequential apostrophes in a quoted string denote a single character, namely an apostrophe.
串中连续的两个单引号表示一个字符，即单引号。
For instance, what about matching words containing an apostrophe (') character—don't, who're, e'er, owner's, 'cause, Joe's, and so on?
例如，对于包含撇号 (') 字符 — 的单词（如 don't、who're、e'er、owner's、'cause、Joe's 等等）如何处理呢？
Use the following character map to prevent escaping all ampersand (&), less than (greater than (>), apostrophe ('), and double quote (") characters.
使用下列字符映射避免转义所有的与符号（&）、小于号（大于号（>）、单引号（'）和双引号（"）字符。
