http://bugs.kde.org/show_bug.cgi?id=136062         
           Summary: Charset problem saving EXIV comments (JPEG files)
           Product: digikam
           Version: 0.9.0-beta2
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: valerio.fuoglio kdemail net


Version:           0.9.0-beta2 (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          gcc version 4.1.1 (Gentoo 4.1.1-r1)
OS:                Linux

Digikam saves erroneously some characters in JPEG comments.

----------------------------------------------------------
Examples:

Comments inserted with digikam:
-Digikam comments: "Questa è una prova di commento"
-Exiv comments: "Questa Ú una prova di commento"
Character "è" will be saved as "Ú".

Comments inserted exiv2 (exiv2 -c "my comments" myfile.jpg)
-Exiv comments: "Prova é à ù è ì @ ò"
-Digikam comments: ""
-----------------------------------------------------------

Other problem: comments inserted by exiv2 (or another image manager) will not be shown in digikam.(should I submit a new bug?)

Here are two different issues.
First: UTF8. The image comment (JFIF comment) is saved as UTF8, and UTF8 saves non-ASCII characters in two bytes.

Second: Reading comments to the database. This is only done after importing the image for the first time. After that, the comment is read from the database.
Is that what you mean?

See http://mail.kde.org/pipermail/digikam-users/2006-October/002116.html for information on how digikam handles the various possibilities to store the comment in an image.

First: OK

Second: You mean that, if I edit exiv tags with another images manager, those images needs to be re-imported in digikam?

Thanks for the link, I'll take a look ASAP.

Hi Gilles, I've made these tests with SVN (trunk) digikam:

Save comments in digikam --> read with exiv from command line --> No problem

Save comments from command line (exiv2) --> read with digikam --> No change made. (Digikam doesn't update its database)

Is it the expected behaviour?

Valerio,

Yes it's normal because something is missing in digiKam core about this problem. There is another file in B.K.O about it...

But the problem of this file is charset. It look fine. Right ?
