Paragraph sign character from ISO-8859-1 PostGis DB problem

Having a paragraph or section sign '§' in a iso-8859-1 PostGis table and querying the data per WFS results in the following error and chopped geoserver output from the problematic char on. I can only receive the result XML up to the § char. Changing GeoServer charset from UTF-8 to ISO-8859-1 doesnt help.

Request: getFeature
