This module will sort text in the อักษรจีน. It is used to sort Ai-Cham, อามามิโอชิมะใต้, Central Bai, Panyi Bai, Southern Bai, Biao-Jiao Mien, Biyo, หมิ่นตะวันออก, จิ้น, จีนกลาง, ผิงเหนือ, Chinese Pidgin English, ผูเซียน, Macau Pidgin Portuguese, ผิงใต้, Huizhou, หมิ่นตอนกลาง, ดุงกาน, Daur, E, กั้น, แคะ, Yemaek, ไหหลำ, เซียง, ญี่ปุ่น, Hachijō, Kikai, Lama Bai, จีนยุคกลาง, หล่อยแอว๋, จีนวรรณกรรม, Jie, Rouran, Tuyuhun, Tuoba, Wuhuan, Xianbei, Xiongnu, เวียดนามกลาง, Caolan, หมิ่นเหนือ, ร่วม, มิยาโกะ, หมิ่นใต้, Datian Min, ฮกเกี้ยน, Hailufeng Min, Longyan Min, แต้จิ๋ว, Zhenan Min, Sanxiang Min, นุง, จีนเก่า, ญี่ปุ่นเก่า, โอกิโนเอราบุ, อุยกูร์เก่า, ปู้อี, แพ็กเจ, อามามิโอชิมะเหนือ, ยาเอยามะ, โอกินาวะ, Shaojiang Min, สุ่ย, Bailang, โทกูโนชิมะ, Alchuka, Bala, Kyakala, ตั่ย, เวียดนาม, อู๋, Waxiang, ทิเบตคลาสสิก, มองโกเลียกลาง, Buyeo, คูนิงามิ, โยนางูนิ, โยรง, กวางตุ้ง, จ้วง, Zauzou, จีน, Shaozhou Tuhua, เสฉวน, ห่อยซัน, Goguryeo, Zakhring, คีตัน, และ Gaya. 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.

The demonstration functions that generated the content shown below are housed in Module:Hani-sortkey/templates. Modifications to the module can be tested in Module:Hani-sortkey/sandbox. Sortkeys for individual characters are retrieved from one of 178 data modules. Module:Hani-sortkey/data creates documentation for these modules.
