** exif:ImageDescription: ..:\w.*According to the Exif spec (http://www.cipa.jp/std/documents/e/DC-008-2012_E.pdf), even UTF-8 should be invalid. This field is supposed to be ASCII only apparently (yes that's sucky, definitely). To use multi-byte encoding, such as UTF-8 (or others such as JIS), the right field is UserComment.
To make matters worse, the MWG guidelines [0] state that "Exif tags documented in the Exif specification as type ASCII SHOULD be written as UTF-8". [...]
All this said, it would be good if GIMP were more robust to otherwise-valid images, even with buggy metadata. In particular, it should not fail to export, but simply discard the wrong metadata field with a warning.
Or just copy the content verbatim, there might be a reason for it being the way it is.
Could you please open a bug report about this issue so that we look into this issue? Thanks! Jehan
