Although many (particularly older) VGAs have identical characters in their ROMs (there are some minor inconsistencies, like the digit zero -- slashed or with a dot inside), there are also a lot of VGAs from different vendors that have much different typefaces in their ROMs (e.g., ATI SVGAs, Chips & Technologies LCD controllers, and probably many others -- I just mention those I work(ed) with). On the other hand, the BIOS character recognition code should take into account the actual character definitions, not the ROMmed ones (there is a BIOS pointer for this purpose). But I admit, I never verified how the real BIOSes behave in that point. BTW, "official" .CPI files differ slightly between MS-DOS and DR-DOS even for ASCII characters 32..127.
