XnView Software

It should be good to edit some Exif items:
Exif.Image.Artist
Exif.Image.XPAuthor - it is shown in Windows Explorer properties, but there is problem with special coding UCS2
Exif.Image.XPKeywords - it is shown in Windows Explorer properties, but there is problem with special coding UCS2

GeBu, why don't you just use Phil Harvey's ExifTool? It does the text-to-byte translation for XP tags on the command line without any fuss, and while it may be slower than Andreas Huggel's "Exiv2," it also happened to have the custom tags for iView Media Pro and, I believe Apple's Aperture, well before Andreas had the former or the pyexiv2 guys the latter.
