Well, NO, it works , but it updates ANOTHER field, the "Comment" one, NOT the "XP Comment" one.

just run these on a "clean" .jpg

exiftool dst.jpg
exiftool -Comment="This is a new comment in the comment field" dst.jpg
exiftool dst.jpg
exiftool -XPComment="This is a new comment in the XP comment field" dst.jpg
exiftool dst.jpg

P.S.: if this:

is not "accurate" enough, try this:

and particularly this :

Thanks very much.

can not support Chinese characters:

d:\exiftool-7.57>exiftool -XPComment="测试" dst.jpg

Malformed UTF-8 character (1 byte, need 2, after start byte 0xd4) in unpack in I

FD0:XPComment (ValueConvInv)

Nothing to do.

can not support Chinese characters:

Hmm

http://www.sno.phy.queensu.ca/~phil/exifto...Names/EXIF.html

(tags 0x9c9b-0x9c9f are used by Windows Explorer; special characters in these values are converted to UTF-8 by default, or Windows Latin1 with the -L option. XPTitle is ignored by Windows Explorer if ImageDescription exists)

Could it be some kind of mis-match with codepage in the CMD window or something weird like ANSI/ASCII? (read DOS as opposed to Windows source)

Try the other way, i.e. put your comment with XP GUI on the image and read it through EXIF.

It is possible that a conversion is needed.....

Or try putting your comment in notepad and save it as UTF-8, then "feed" the file to EXIF through redirection....

P.S.: I guess you can use chcp and python:

but not really my field.

I guess that on Chinese Forums this problem has come out and has been resolved already.
