Preprocessor (cl -E) limits ? (Error C2018 )

Xavier Roche

Does anyone know why certain characters are permitted in a 8-bit source
file when using cl -E and not others ?

Example 1:
----------

#define Foo() Holà, Mundo!
Foo()

cl -E -P foo.c
cat foo.i

#line 1 "foo.c"

Holà, Mundo!

Example 2:
----------

#define ThreeQuarters() This is a ¾!
ThreeQuarters()

cl -E -P foo.c
foo.c(2) : error C2018: unknown character '0xbe'

This is not an UTF-8 limit problem ("Holà, Mundo!" is definitely NOT a
valid UTF-8 sequence), so where's the problem?

(note: yes, this is not a valid C source, but I'm just using the
preprocessor)
