> I have a small input JPEG image containing _no metadata sections whatsoever_. I use Apache Commons Imaging 1.0-alpha2 to add two simple Exif {{IFD0}} properties using [`ExifRewriter().updateExifMetadataLossy()`|https://commons.apache.org/proper/commons-imaging/apidocs/org/apache/commons/imaging/formats/jpeg/exif/ExifRewriter.html#updateExifMetadataLossy-org.apache.commons.imaging.common.bytesource.ByteSource-java.io.OutputStream-org.apache.commons.imaging.formats.tiff.write.TiffOutputSet-].
> * {{XPTitle}}  ({{0x9C9B}}): "Gate and Turret"
> * {{Copyright}} ({{33432}}, {{0x8298}}): "Copyright © 2009 Garret Wilson"
> Here is a simplified excerpt of the code:
> {code:java}
> TagInfoAscii EXIF_XP_TITLE_TAG_INFO = new TagInfoAscii("XPTitle", 0x9C9B, -1, TiffDirectoryType.EXIF_DIRECTORY_IFD0); //XPTitle (0x9C9B)
> TagInfoAscii EXIF_COPYRIGHT_TAG_INFO = new TagInfoAscii("Copyright", 0x8298, -1, TiffDirectoryType.EXIF_DIRECTORY_IFD0); //Copyright (33432, 0x8298)
> …
> TiffOutputSet tiffOutputSet = new TiffOutputSet();
> TiffOutputDirectory exifDirectory = tiffOutputSet.getOrCreateRootDirectory();
> exifDirectory.add(EXIF_XP_TITLE_TAG_INFO, "Gate and Turret");
> exifDirectory.add(EXIF_COPYRIGHT_TAG_INFO, "Copyright © 2009 Garret Wilson");
> …
> new ExifRewriter().updateExifMetadataLossy(byteSource, outputStream, tiffOutputSet);
> {code}
> Using [ExifTool|https://exiftool.org/] 12.16 (via [ExifToolGUI|https://exiftool.org/gui/) 5.16.0.0], the {{Copyright}} value is stored correctly but the {{XPTitle}} is stored as "慇整愠摮吠牵敲t". [Metadata++|https://www.logipole.com/metadata++-en.htm] 1.22.14 also shows the same corrupted value.
> This is disheartening, as this is nearly the most simple test case possible.
> (Note that [IrfanView|https://www.irfanview.com/] 4.54 can read the {{XPTitle}} just fine! Nevertheless ExifTool is the gold standard for image metadata reading, and is confirmed by Metadata++. Having an image that cannot be read in ExifTool is a show-stopper.)
> I'm will attach the test case image to this ticket.
