Output tag charset

[José Oliver-Didier]

I wish to check what charset was used on certain EXIF tags (Example: ASCII or UTF-8). Is there a way to display in the output charset encoding for tags?

[Phil Harvey]

If ExifTool knows the encoding then it automatically converts it to UTF-8 by default when extracting information (or to whatever character set you specify with the -charset option.  But if ExifTool doesn't know the character set, it can't do this, and the output encoding is indeterminate.
