Use UTF-8 instead. It’s understood by every self-respected client side and server side operating system platform. It’s also considered the standard character encoding these days. Tomcat still defaults to the old ISO 8859-1 charset as to decoding GET request parameters and to the server platform default encoding as to decoding POST request parameters. To set … Read more
