Hi,
For context: I am calling exiftool from Dart, and on some files when I do:
exiftool -charset exiftool=UTF8 -G -s -a "/Users/me/Pictures/Tests/2012.07 - Test/20120722_175913.jpg"
Dart is complaining about
FormatException: Invalid UTF-8 byte (at offset 2826)
I tried using the -charset switch in order to avoid it but no dice.
I also redirected the output to a file, but Atom seems to have no problem with it and recognizes it as UTF-8.
I did try to read everything though, and it might be the field "UserComment" that contains some weird stuff.
[EXIF] UserComment : .�.;
/context
For this reason I want to either:
- find a way to output valid UTF-8 text (that Dart accepts, maybe Dart has its own quirks, but I don't expect you to give me fixes for Dart or my Dart code :)
or
- ignore the field when I retrieve the exif data for the file (since I'm currently only interested in the date/time and location fields, I could only extract those, but if possible I would prefer to extract the maximum amount of information)
Thank you for your reply.
The normal ExifTool output isn't guaranteed to have a known character set. You must use one of the JSON, CSV or XML output formats (-j, -csv or -X) if you want to guarantee this.

Can I exclude a single field then ?
I'd rather not have to do the extra leg work of processing JSON (which would still be preferable to CSV or XML :)
Thanks.
I have found somewhere else on the forum the answer:
using
--UserComment
leaves out the comment field and no longer results in an error.
