Swedish characters are garbled in form
--------------------------------------

                 Key: PDFBOX-932
                 URL: https://issues.apache.org/jira/browse/PDFBOX-932
             Project: PDFBox
          Issue Type: Bug
          Components: PDModel.AcroForm
    Affects Versions: 1.4.0
         Environment: Mac OSX, Java6
            Reporter: Pär Wenåker


When using swedish characters to fill in a form they show up garbled in the 
PDF. This seems to have to do with the PDAppearance class. When calling 
setValue on the field, the value seems to be set ok since COSString handles 
characters outside ASCII in its writePDF method. When PDAppearance writes the 
value in insertGeneratedAppearance it does not do the same check. If the same 
check is done it seems to work for PDAppearance to (see patch below). Since I 
do not know very much about the PDF format, I dont know if this is the right 
way to do it...

        PDDocument document = PDDocument.load(<pdf-file>);
        PDDocumentCatalog docCatalog = document.getDocumentCatalog();
        PDAcroForm form = docCatalog.getAcroForm();
        PDField field = form.getField(<field name>);
        field.setValue("åäö");
