> When a resource is added using {{KieHelper.addResource}}, any specified encoding is ignored when it is added to the {{MemoryFileSystem}} by {{KieFileSystemImpl.write(Resource)}} (effectively assuming the {{InputStream}} is already encoded in UTF-8).
> Additionally, when the resource is read again by {{AbstractKieModule.getResource}}, it constructs a {{Resource}} object with no encoding specified, whereas it should probably specify an encoding of UTF-8, since it seems that sources are considered to be UTF-8 already at least in the case of the {{MemoryKieModule}}.
> I've attached a fairly minimal test case where the rules bytes are passed in UTF-8 with the encoding explicitly specified. This currently produces an error when the default file encoding is not UTF-8 (eg, by passing {{-Dfile.encoding=latin1}} as a JVM argument, or by using the default arguments on Windows).
