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

> 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");
