众所周知，WordPress中文版有个特性，会将每一处英文引号（""）都稀里哗啦转化为中文引号（“”）。不仅仅是英文引号，在WordPress翻译文件定义了不少自动转换符号，具体可以参考这里。
对文字博客来说，这是个好功能，这样会避免用错英文标点。
然而，WordPress是独立的php程序，中文社区中懂得使用者，大部分都是技术博客。而技术博客会经常贴出代码，里面包含各种英文标点是再正常不过的事情。这时候，英文标点符号自动转换就是一个恼人的画蛇添足功能了。
网上很多文章都是让该WordPress核心文件。只不过，WordPress是一个高度模块化的系统，肯定有更优雅的解决方案。
一番搜寻之后，发现最简单的办法，就是安装一个叫Quotmarks Replacer的插件，地址在这里。
插件很简单，就是将WordPress自动转换标点符号的函数用系统接口去掉。核心代码如下：
<?php
