It is beyond ludicrous for functions like chr() or ascii() to convert a
Euro sign to 0xE282AC rather than 0x20AC. "Intuitive"? There is _NO SUCH
THING_ as 0xE282AC as a representation of a Unicode character - there is
either the code point, 0x20AC (which is a _number_), or the sequences of
_bytes_ that represent that code point in various encodings, of which the
three-byte sequence 0xE2 0x82 0xAC is the one used in UTF-8.

Functions like chr() and ascii() should be dealing with the _number_ of the
code point, not with its representation in transfer encodings.
