Synopsis

http {
    url_encoding_convert               on;
    url_encoding_convert_from          utf-8;
    url_encoding_convert_to            euc-kr;

Description

This is an Nginx module that converts the encoding of characters in requested uri into user defined encoding(charset). That is to convert uri to user defined encoding before accessing a file of the uri. This module does work, if the requested file does not exist. For example, nginx's configuration is as above, if the server's file name is "한글.txt" encoded to euc-kr and client's requested uri is "/한글.txt" encoded to utf-8 and the requested uri is changed to euc-kr by the module before access to the file to generate content. This module's working phase can be changed according to the directive url_encoding_convert_phase's option.
