Let’ see an example to understand UTF-8 string encode behavior. This is the problem if we don’t use the UTF-8 encoding.īut when we convert an ASCII-encoded string that uses all the English characters to UTF-8 then we get the same string. Here you can see this string encoded using US_ASCII gives us the value “Entwickeln Sie mit Vergn��gen” when printed because it does not understand the non-ASCII ü character. ('ASCII encoded string is ::' + asciiEncodedString) German string is :: Entwickeln Sie mit VergnügenĪSCII encoded string is ::Entwickeln Sie mit Vergn��gen String asciiEncodedString = new String(germanBytes, StandardCharsets.US_ASCII)

String germanString = 'Entwickeln Sie mit Vergnügen' īyte germanBytes = germanString.getBytes() Below is the sample code snippet for this. To understand the problem with the encoding, we will work with the German String “Entwickeln Sie mit Vergnügen”. What is the problem with the ASCII encoding? For example, suppose we want to encode a string to UTF-8 in Java. Sometimes in applications or projects when we are dealing with the strings in Java then we need to encode them in a specific charset. Overview to Encode String to UTF-8 Problem

This tutorial will help you to understand the problem statement of how to encode a string to UTF-8 in Java and then we will see the solution to this. We will see the solution with core Java and with the help of some third-party libraries. Then this Controller will dispatch the request based on the requested URL, for example, if client asks for register.do, Controller will dispatch the request to Register.java.Īnd in the Register.In this tutorial, we will learn how to encode a string to UTF-8 in Java. So in web.xml, I have a Controller servlet which takes all request from *.do. I am using a Servlet called Controller.java to handle all request.

I am developing a simple web application using java/jsp/tomcat/mysql, and the most problem lies on the character encoding because I need to deal with UTF-8 encoding instead of the default 8851.įirst of I'd like to describe my program structure.
