zhconv-rs converts Chinese text among several scripts or regional variants (e.g. zh-TW <-> zh-CN <-> zh-HK <-> zh-Hans <-> zh-Hant), built on the top of zhConversion.php conversion tables from Mediawiki, which is the one also used on Chinese Wikipedia.

| Target | Tag | Script | Description |
| -------------------------------------- | --------- | ------- | --------------------------------------------- |
| Simplified Chinese / 简体中文 | zh-Hans | SC / 简 | W/O substituing region-specific phrases. |
| Traditional Chinese / 繁體中文 | zh-Hant | TC / 繁 | W/O substituing region-specific phrases. |
| Chinese (Taiwan) / 臺灣正體 | zh-TW | TC / 繁 | With Taiwan-specific phrases adapted. |
| Chinese (Hong Kong) / 香港繁體 | zh-HK | TC / 繁 | With Hong Kong-specific phrases adapted. |
| Chinese (Macau) / 澳门繁體 | zh-MO | TC / 繁 | Same as zh-HK for now. |
| Chinese (Mainland China) / 大陆简体 | zh-CN | SC / 简 | With mainland China-specific phrases adapted. |
| Chinese (Singapore) / 新加坡简体 | zh-SG | SC / 简 | Same as zh-CN for now. |
| Chinese (Malaysia) / 大马简体 | zh-MY | SC / 简 | Same as zh-CN for now. |
Note: zh-TW and zh-HK are based on zh-Hant. zh-CN are based on zh-Hans. Currently, zh-MO shares the same conversion table with zh-HK unless additonal rules / CGroups are applied; zh-MY and zh-SG shares the same conversion table withzh-CN unless additional rules / CGroups are applied.

ZhConver{sion,ter}.php of MediaWiki: zhconv-rs are just based on conversion tables listed in ZhConversion.php. MediaWiki relies the PHP built-in function strtr, which is inefficient. zhconv-rs ports some of the implementation of MediaWiki to supports the same conversion rule syntax with much more efficiency.All of these implementation shares the same leftmost-longest matching strategy. So conversion results should generally be the same given the same conversion tables.
