Normal BIOS console supports only CP437. The fix for this would go through: 1) Possible use of vga_text instead of BIOS services and enhance it with font-loading code to dynamically load characters we need. But this is already more than just a simple console and requires to load e.g. unifont. Currently BIOS services and vga_text are used for their simplicity and compactness. Perhaps vga_text would need to be split to vga_text and vga_text_font the latter being a separate module and vga_text calling vga_text_font only if it's loaded. 2) Another possibility is to translate the unrepresentable characters to their nearest ASCII equivalent. The problem is that this is somewhat language-dependent. E.g. a German-speaking person would replace ö with oe but a Finnish would probably just drop the diaresis. > -andrey > > > _______________________________________________ > Grub-devel mailing list > Grub-devel@gnu.org > https://lists.gnu.org/mailman/listinfo/grub-devel > -- Regards Vladimir 'φ-coder/phcoder' Serbinenko
