/**
* Copyright 2014-2017 Piet Bos (email : piet@so-wp.com)
*
* The SO Pinyin Slugs plugin is a fork of the original [Pinyin Permalinks](http://wordpress.org/plugins/pinyin-permalink/) plugin
* by user [xiaole_tao](http://profiles.wordpress.org/xiaole_tao/) who has seemingly abandoned his plugin as he never responded to emails.
*
* My ex-colleague [Denis Cao](https://github.com/caoyongsheng) has adapted the original plugin in such a way that when the plugin is used
* on bi/multilingual websites (for example with WPML), it leaves the slugs of the non-Chinese languages intact.
