Hello

I am trying to change the XMP metadata in JPG files but Xmp.Save() method generates an error if the XmpValueNode's value contains any swedish non ASCII charater. It works if i convert the string to 7-bit ASCII but if i do that the 'Å' is replaced by '?' in Photoshop.

Is this a bug or am I doing something wrong?

/Martin

Code:

LosslessJpegTransform JT = new LosslessJpegTransform(InputFile);
XmpData Xmp;
if (JT.Xmp != null)
    Xmp = new XmpData(JT.Xmp);
else
    Xmp = new XmpData();

XmpValueNode Node = new XmpValueNode(XmpNodeType.SimpleProperty, "Åkesson", XmpTagNames.DCTitle);
if (Xmp.Contains(Node))
    Xmp[XmpTagNames.DCTitle] = Node;
else
    Xmp.Add(XmpTagNames.DCTitle, Node);

JT.Xmp = Xmp.Save();    // <------Throws the error "External component has thrown an exception."
JT.Write(OutputFile);
