Class Utf8EncodingFilter

java.lang.Object

me.nickhanson.codeforge.web.Utf8EncodingFilter

All Implemented Interfaces:

jakarta.servlet.Filter

@WebFilter("/*")
public class Utf8EncodingFilter
extends Object
implements jakarta.servlet.Filter

A servlet filter that sets the character encoding for requests and responses to UTF-8. This ensures that all incoming and outgoing data is properly encoded in UTF-8. Had to add this filter because Tomcat was not correctly setting UTF-8 encoding on POST requests and I wanted to be able to use UTF-8 characters in form submissions--specifically emojis. lol
