<p>While reading a QR code (Swiss Invoice) form import these characters (ü, ö, ä) are not recognize correclty and had to be adapted manually while storing the document. Is there any OCR configuration or any other solution that could resolve this issue? I tried to configure a custom OCR configuration but din't work. I found the <a href="https://support.docuware.com/en-us/knowledgebase/article/KBA-35851">KBA-35851</a> that is related to my problem but I don't understand where to encode the QR code as unicode UTF8 or encode the value as ISO-8859-1.</p>
