RestEasy client does not use correct encoding - resteasy

Question

I'm using RestEasy as a client to read news from a service.
ResteasyClient listClient = new ResteasyClientBuilder().build();
ResteasyWebTarget listTarget = listClient.target("https://someservice.com/file.xml");
Response r = listTarget.request().get();
final HexMl feedList = r.readEntity(HexMl.class);
The service does not return an encoding or media type in the response header, only an encoding in the xml itself
<?xml version="1.0" encoding="windows-1252"?>
RestEasy does not seem to evaluate this so I get an exception:
javax.ws.rs.ProcessingException: org.jboss.resteasy.plugins.providers.jaxb.JAXBUnmarshalException: javax.xml.bind.UnmarshalException
- with linked exception:
[org.xml.sax.SAXParseException; lineNumber: 116; columnNumber: 30; Invalid byte 2 of 3-byte UTF-8 sequence.]

Is there a way to overwrite the encoding RestEasy uses or intercept the response before the entity is read?
I tried
Response r = listTarget.request().accept(APPLICATION_XML + ";charset=windows-1252").get();
and
Response r = listTarget.request(APPLICATION_XML + ";charset=windows-1252").get();
and
#Consumes(APPLICATION_XML + ";charset=windows-1252")
public class HexMl { ... }
without success. The XML itself seems to be correctly encoded in windows-1252.

For now I'm using a ReaderInterceptor, but this doesn't seem right. So I'd still be glad about better suggestions.
ResteasyClientBuilder clientBuilder = new ResteasyClientBuilder();
ResteasyProviderFactory providerFactory = new ResteasyProviderFactory();
RegisterBuiltin.register( providerFactory );
providerFactory.getClientReaderInterceptorRegistry().registerSingleton( new ReaderInterceptor() {
#Override
public Object aroundReadFrom(ReaderInterceptorContext context) throws IOException, WebApplicationException {
InputStream is = context.getInputStream();
String responseBody = IOUtils.toString( is , "windows-1252");
LOGGER.debug( "received response:\n{}\n\n", responseBody );
context.setInputStream( new ByteArrayInputStream( responseBody.getBytes() ) );
return context.proceed();
}
} );
clientBuilder.providerFactory( providerFactory );
Then I use this clientBuilder to create my client.
