in java.net.URLEncoder The
public static String encode (String s, String enc) method, where the enc (character encoding name) determines which character set to use?
after encoding according to the relevant character set, how can I send it to IE,IE to know which character set to use for decoding?
its function is to convert the character s you enter into the byte [] of the enc encoding format (utf-8 is recommended in jdk) and then convert the corresponding URL encoding characters
the browser itself can parse these URL codes

URIEncoding="UTF-8"
protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />2. Confirm which encoding format your front-end page chooses
