Hello I've encountered a problem while processing some images with exiftool. While my Windows explorer (Win7) didn't show any signs of corrupted data, with exiftool I've discovered that the XPcomment tag was corrupted/damaged (it was the tag which I was working with). As you can see on the left the XP Comment tag appear with weird symbols while on the right the explorer window shows the data correctly. What could cause this problem and how I can fix it? Thanks.
