This module will sort text in the 漢字. It is used to sort 錦語、南奄美大島語、中部白語、北部白語、南部白語、標敏語、碧約語、閩東語、晉語、官話、北部平話、洋涇浜英語、莆仙語、澳門皮欽葡萄牙語、南部平話、徽語、閩中語、東干語、達斡爾語、誒話、贛語、客家語、湘語、日語、八丈語、喜界語、拉瑪白語、中古漢語、文言文、中古越南語、高欄語、閩北語、跨語言、宮古語、閩南語、泉漳話、海南話、雷州話、潮州話、儂語、上古漢語、古典日語、沖永良部語、古回鶻語、布依語、百濟語、柔然語、吐谷渾語、拓跋語、烏桓語、鮮卑語、北奄美大島語、八重山語、沖繩語、水語、白狼語、德之島語、阿勒楚喀語、巴拉語、恰喀拉語、岱依語、羯語、越南語、吳語、瓦鄉話、古典藏語、中古蒙古語、扶餘語、國頭語、與那國語、與論語、粵語、壯語、柔若語、漢語、韶州土話、四川話、台山話、高句麗語、扎話, 和契丹語. The module should preferably not be called directly from templates or other modules. To use it from a template, use {{sortkey}}. Within a module, use Module:languages#Language:makeSortKey.

For testcases, see Module:Hani-sortkey/testcases.

Functions

makeSortKey(text, lang, sc): Generates a sortkey for a given piece of text written in the script specified by the code sc, and language specified by the code lang.; When the sort fails, returns nil.

產生如下所示內容的示範函數位於Module:Hani-sortkey/templates中。模組的修改可以在Module:Hani-sortkey/sandbox中進行測試。單一字元的排序鍵是從178個資料模組之一檢索的。Module:Hani-sortkey/data為這些模組建立文件。
