Hi Tilman, I tested pdfbox-3.0.8-20260323.163747-15 and update the value of field "Geschlecht" to "männlich". The issue is half fixed.
Fixed: The appearance name (/AP) "/m#e4nnlich" is not renamed any more. Great work! Not fixed: - But the value (/V) of the field is still being encoded as "/m#c3#a4nnlich". The same name as in /AP must be used here, right? - And the selected appearance (/AS) of the field is not changed to "/m#e4nnlich". It remains "/Off". The field is not selected visually on the rendered page. The result file: https://signotecgmbh-my.sharepoint.com/:b:/g/personal/markus_mensinger_signotec_de/IQC6ZpRWlFX4R5nY4rHk7DP8AcNO-Gl1dvTBBt6OTTCTU7U?e=cgfqS1 Kind regards Markus > -----Ursprüngliche Nachricht----- > Von: Tilman Hausherr <[email protected]> > Gesendet: Dienstag, 24.
