* font/font.c: Include `ascii.h'. (ASCII_BITMAP_SIZE): New macro. (ascii_font_glyph): Define. (ascii_glyph_lookup): New function. (grub_font_get_string_width): Change comment. If glyph not found, use ascii_glyph_lookup. (grub_font_get_glyph_with_fallback): If glyph not available returns ascii_glyph_lookup. * util/grub-mkfont.c (file_formats): New enum. (options): Add `ascii-bitmaps' new option. (usage): Add `asii-bitmaps' new option. (write_font_ascii_bitmap): New function. (write_font): Rename to ... (write_font_p2): ... this. Remove print_glyphs call. (main): Use file_format. Implement code for ranges if ascii-bitmaps is used. Call print_glyphs. * Makefile.in (pkgdata_DATA): Add `font/ascii.h'.
