UTF8 tags in EXIF

When copying UTF8 tags in EXIF (e.g. comments created in Picasa) between files, use explicit charset specification:

for i in *JPG 
 do
  exiftool -iptc:codedcharacterset=utf8 -charset UTF8 \

           -overwrite_original -tagsfromfile=../"$i" "$i" 
done

Some tags are re-encoded as Latin (windows) by default, even without -L option. The -iptc switch makes the trick.
