# 24. 語系

本章從管理員的角度描述可用的本地化語系功能。PostgreSQL 支援兩種本地化的功能：

* 使用作業系統的區域設定功能來提供特定於語言環境的資料排序、數字格式、翻譯的訊息和其他方面。這在[第 24.1 節](/15/server-administration/localization/locale-support.md)和[第 24.2 節](/15/server-administration/localization/collation-support.md)中有介紹。
* 提供許多不同的字元集以支援各種語言的儲存檔案，並在用戶端和伺服器之間提供字元集轉換。這在[第 24.3 節](/15/server-administration/localization/character-set-support.md)中有介紹。
