Play! Framework 2.5 form encoding

After upgrading from Play! 2.4 to Play! 2.5 there seems to be a problem with form-enconding. German umlauts for example really get messed up. For example the german word "Bär" becomes "Bär". I already changed the way I access form data from 

Form.form(Form.class).bindFromRequest();

to the injected way, as described in the migration guide:

formFactory.form(Form.class).bindFromRequest();

Is there a was to fix the character encoding in Play 2.5?

This is a bug in play 2.5 , see github issue: https://github.com/playframework/playframework/pull/5920

I resolve this with a custom body parser:

   package com.kashi.ssff.services;

import akka.util.ByteString;
import play.api.http.HttpConfiguration;
import play.core.parsers.FormUrlEncodedParser;
import play.http.HttpErrorHandler;
import play.libs.F;
import play.libs.streams.Accumulator;
import play.mvc.BodyParser;
import play.mvc.BodyParsers;
import play.mvc.Http;
import play.mvc.Result;

import javax.inject.Inject;
import java.util.Map;

/**

 */
public class FormBodyParser extends BodyParser.BufferingBodyParser<Map<String, String[]>> {
    private final HttpErrorHandler errorHandler;

    public FormBodyParser(long maxLength, HttpErrorHandler errorHandler) {
        super(maxLength, errorHandler, "Error parsing form");
        this.errorHandler = errorHandler;
    }

    @Inject
    public FormBodyParser(HttpConfiguration httpConfiguration, HttpErrorHandler errorHandler) {
        super(httpConfiguration, errorHandler, "Error parsing form");
        this.errorHandler = errorHandler;
    }

    @Override
    public Accumulator<ByteString, F.Either<Result, Map<String, String[]>>> apply(Http.RequestHeader request) {
        return BodyParsers.validateContentType(errorHandler, request, "Expected application/x-www-form-urlencoded",
                ct -> ct.equalsIgnoreCase("application/x-www-form-urlencoded"), super::apply);
    }

    @Override
    protected Map<String, String[]> parse(Http.RequestHeader request, ByteString bytes) throws Exception {
        String charset = request.charset().orElse("UTF-8");
        return FormUrlEncodedParser.parseAsJavaArrayValues(bytes.decodeString(charset), charset);
    }
}

and annotate controller with this body parser:

    @BodyParser.Of(FormBodyParser.class)
    public Result register() {
.
.
.

in your form try adding the accept-charset="ISO-8859-1"

<form  accept-charset="ISO-8859-1" action="whatever" method="post">

tested it for the word Bär and it works fine

EDIT:

For the arabic script the characters are stored as ISO-8859-1 encoded as well. An image to show that at the end all goes well.
