Every conforming implementation is required to support the basic source
character set. It's also required to support an extended source
character set - but it gets to define what the extensions are - there
need not be any difference between the basic and extended source
character sets.

Note, however, that the minimum number of different char values is 255
(if CHAR_BIT==8, and char is a signed type using 1's complement or
sign-magnitude representation, so that CHAR_MAX == 127, CHAR_MIN==-127).
That's much larger than the size of the basic character set, so there
must be char values that don't represent any member of the basic
character set.

"The source character set may contain multibyte characters, used to
represent members of the extended character set. The execution character
set may also contain multibyte characters, ..." (5.2.1.2p1). Note the
use of the word "may" - a conforming implementation need not have any
such characters, in either the source or execution character sets.

No.
