Static data and localisation

[jim-easterbrook]

Looking at the source file datasets.cpp I noticed that the initialisation of static data such as application2Record[] includes localisation (or localization if you prefer) markers, e.g.

        DataSet(IptcDataSets::ObjectName, "ObjectName", N_("Object Name"),
                N_("Used as a shorthand reference for the object. Changes to exist-ing "
                "data, such as updated stories or new crops on photos, should be "
                "identified in tag <EditStatus>."),
                false, false, 0, 64, Exiv2::string, IptcDataSets::application2,
                N_("Document Title")),

My C/C++ knowledge is limited, but I think that that data is fixed at compile time, so the strings aren't localised when my localised application accesses the static data. I can get the localised version of each string by calling Exiv2::exvGettext with the English text. (The value returned by Exiv2::IptcDataSets::recordDesc is also not localised.)

Is this expected behaviour and I should carry on and use Exiv2::exvGettext where needed, or am I doing something wrong with my initialisation of libexiv2? I'm using my Python interface python-exiv2 for all this, so that is a possibility. Error messages from libexiv2 are localised though.
