In my C program I’ve had to swap my unicode box-drawing characters into escaped

  • 0

In my C program I’ve had to swap my unicode box-drawing characters into escaped characters for DOS code page 437 to get it to work in the Windows command prompt. Is it possible to change the code page of gnome-terminal to display these characters correctly when natively compiling the program for linux?

Thanks.

    The current gnome-terminal does not
    have a setting for code page 437, but
    it does support other code pages that
    are equivalent for NetHack’s purposes,
    such as 862 (Hebrew).

    To set code page 862 on
    gnome-terminal:

    • Select Terminal->Set Character Encoding->Add or Remove.
    • In the pane on the left, select the line with description Hebrew and
      encoding IBM862.
    • Click the right-pointing arrow between the two panes.
    • Click Close.

    The above steps only need to be done
    once for the lifetime of the Gnome
    installation. Once done, it is
    sufficient to:

    • Select Terminal, Set Character Encoding, and then Hebrew (IBM862).

    It should be noted that the current
    default gnome-terminal font in Ubuntu
    Jaunty fully supports DECgraphics as
    long as eight_bit_tty is set to false.
