wptexturize( string $text, bool $reset = false )

用格式化的实体替换普通的纯文本字符。
Replaces common plain text characters with formatted entities.

说明（Description）

Description返回给定文本，并将引号转换为智能引号、撇号、破折号、省略号、商标符号和乘法符号。举个例子，因为今天的努力值得明天的“假期”。。。变成：'因为今天的努力使它值得明天的“假日”…某些HTML块中的代码被跳过。不要在“init”操作钩子之前使用此函数；一切都将中断。

 * Becomes:
 *
 *     ’cause today’s effort makes it worth tomorrow’s “holiday” …
 *
 * Code within certain html blocks are skipped.
 *
 * Do not use this function before the 'init' action hook; everything will break.
