Convert ASCII Database Postgresql return to UTF-8 in Java Ksoap

Question

Have app Android that consumes from a webservice where the database is Postgresql and the ASCII type. When I try to print the string returned in the app he defaults the lyrics with accentuation, for example, Pulmão = Pulm?o.

Should I do this conversion on the service or client and what is the command for the case? And I must set something up in Eclipse IDE to accept this command?

Example:

1. My Webservice which is in java makes the query in the postgres database (ASCII) and returns a string/object with the fields. These fields are set in a person type object for example.
2. This object is consumed by the Android application for later viewing. Then if I search the data of the person and came the "John", the "ã" is printed on the disfigured screen. Eclipse is set to UTF-8, so I’m not sure how to handle this problem. I have tried (getbytes(). forname("UTF-8") and others, but error in syntax.

Stretch of return on application:

HttpTransportSE Transport = new HttpTransportSE(URL);
Transport.debug = true;

Transport.call(SOAP_ACTION, envelope);

//Recebendo retorno do Webservice

SoapObject response = (SoapObject)envelope.bodyIn;
