Right. Since one can't count on a particular mapping between integers and characters, the portable use of [0..255] mapping is limited in the way that the programmer treats these characters "opaque", only assuming she can extract the same integer from it as the character is created from. This fact makes me think the use of Scheme character for C FFI that expects C 'char' not very convenient; it'd be easier to pass Scheme integers (and you use ascii->char/ char->ascii in Scheme side, if you wish). Nevertheless, there _might_ be a case that you wish to receive a character from C FFI, and you don't want to get an error when C FFI incidentally returns a code that is not supported by the Scheme implementation. That's why I think I don't need to reject the idea. Such use of 'octet as character' should be used only to handle exceptional cases, though. > We should never need to know what the binary encoding of some > character 'C' is in order to write a .jpg file to disk, but as > matters stand we do.
