When I open tar archive using Ark, select some non-English files, and try to extract, then Ark complains that there are not matched files, and the job fails.

With browsing some codes of Ark, I found such code in arkwidget.cpp file,

ArkWidget::action_extract()
{
   ....
   m_extractList->append(QFile::encodeName(*it));
   ....
}

but I cannot find decoding routine from codes which extract archvies. I think this is the reason why I can't extract non-English files.

So I modified tar.cpp file little bit to decode file names correctly. I modified only tar.cpp, but I think that decoding routing should be applied all file formats supported by Ark.
