('utf8 Encoded String is ::' + utf8EncodedString) String utf8EncodedString = new String(bytes, StandardCharsets.UTF_8) String inputString = 'Entwickeln Sie mit Vergnügen' īyte bytes = inputString.getBytes(StandardCharsets.UTF_8) To achieve the solution of our requirement, we need to copy the bytes of string and then create a new one with the desired encoding ( i.e., utf-8 in our case). Encode String with Core JavaĪs we know Strings are immutable in Java, which means we cannot modify the existing behavior and simply we cannot change the string character encoding. 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. In this tutorial, we will learn how to encode a string to UTF-8 in Java.
