    Hmm, I don't know how current ncurses treat terminfo definition in UTF-8
    mode and what linux terminal definition you are using in you test
    system. There are different definitions floating around in different
    distributions which are slightly different especially as we talk about
    acsc chars and enacs, smacs and rmacs sequences. Which is also wrong
    approach so there should be one proper definition of the linux console.
    Maybe kernel developers should prepare some most compatible and
    acceptable one.
    I can post the one I am using today:

    If using this definition and my patch applied acsc mode is not working
    then there is something wrong in curses code IMHO.
    I am using Ubuntu distro and with this patch and this definition
    aptitude properly displays semigraphics in UTF-8 mode and Midnight
    Commander also works almost correctly (almost because it is not properly
    ported - it displays help using iso-8859-2 help file without conversion
    to UTF-8 so I can see replacement glyphs as it should be but in options
    and menu it uses UTF-8 but incorrectly counts bytes instedad of glyphs
    so screen is not looking properly if there is a multibyte UTF-8 seqence
    used in a line; anyway it's MC bad code not terminal fault).
