Characters larger than 4 bytes are not supported: byte 0xae

This seems a regression in SoapUI 4.6.4 compared to 4.6.3.

This change (Remove property expansions on WSDL and WADL import) has caused the issue

Previous code
return XmlUtils.createXmlObject( load( url ), options );

New code

String content = readCleanWsdlFrom( url );
return XmlUtils.createXmlObject( new ByteArrayInputStream( content.getBytes() ), options );
// unnecessary byte[] conversion, XmlUtils has method with string input

readCleanWsdlFrom
Tools.readAll( load( url ), 0 ).toString(); // --> does not respect the encoding of the file
