It means that a conformant Scheme will be *compelled* to interpret text files as Latin-1, even on systems where that is not the native encoding, unless the user or the system interposes an interpretive layer that cleans up the characters. Why privilege Latin-1 in such a fashion? It's not even the native encoding of the majority of systems out there. It merely happens to be the encoding that contains the bottom 256 Unicode codepoints. > On the other hand, it's upward compatible and sets a stage > for experimentation re I/O paradigms.

It prescribes behavior that the standard did not; for example, it compels a 0x80 byte to be interpreted as U+0080, though on most Windows systems 0x80 encodes U+20A0, the Euro sign. -- Ambassador Trentino: I've said enough.
