pipeline option to exif_read(), which allows users to direct the exif executable to output results in csv rather than json format. This is helpful for use with images whose metadata contains non-UTF-8-encoded characters. As is documented here, ExifTool’s JSON output does not properly handle non-UTF-8 character sets. Setting pipeline="csv" ensures that non-UTF-8 character sets are properly handled, as demonstrated in a new example in ?exif_read.Fixed exif_read() to now allow repeated elements in args=. This can be necessary when (to take one example) a user needs to separately specify the encoding used in the image file names and in the tags respectively. Now, a call like the following works as it should:
exif_read(path = "myimage.jpg",
args = c("-charset", "exiftool=cp850", "-charset", "filename=cp1250"))configure_exiftoolr() to find a local installation of ExifTool now throws an error rather than just a warning, preventing infinite recursion by exif_read() and exif_version().
