Indeed, there is no such requirement. A parser can perfectly well handle
EBCDIC or other non-ASCII-compatible encodings provided a proper declaration
expressed in that encoding is present.
To be sure, some encodings, like US-BSCII, are problematic. US-BSCII is
the same as US-ASCII except that 0x41 is B and 0x42 is A; the trouble
being of course that the string "US-ASCII" encoded in US-ASCII uses the
same bytes as the string "US-BSCII" encoded in US-BSCII. But such a thing
is not likely to happen except through perversity such as this.
