            Bug ID: 324329
           Summary: IPTC encoding problem with non English language
    Classification: Unclassified
           Product: digikam
           Version: 3.3.0
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Metadata
          Assignee: [hidden email]
          Reporter: [hidden email]

If I add a Title and a Caption to a jpg image in Greek the IPTC metadata of
Object Name and Caption-Abstract appear as ???????. If I add some English
characters in the Title or in the Caption they appear ok. I have tested the
IPTC metadata both with exiftool and gwenview.

Reproducible: Always

Steps to Reproduce:
1. Add Title and Captions in a language other than English (Greek for sure) to
an image
2. Apply changes so that metadata is written to the image
3. Open the image with exiftool or gwenview
Actual Results:  
Object Name and Caption-Abstract appear as ???????

Expected Results:  
Object Name and Caption-Abstract should be readable

Forgot to mention. I have some images whose tags I wrote in Greek by using
Digikam 3.1.0. Greek metadata appears fine for those images in gwenview.

IPTC is a very old standard which only support ASCII characters and strings
size limitations.

XMP is the replacement,  with no limit. It support UTF-8 encoding.

To resume : use XMP instead...

I have also tried XMP. When I see the metadata in gwenview in the Meta
Infrormation panel I get

Title: lang="x-default" My title here
Image Description: lang="x-default" My description here

lang="x-default" appearing there is a bug of gwenview or this is the way it is
supposed to appear?
