Understatement of the decade.

The Standard does not permit use of any character other than _, 0-9, a-z,
and A-Z in identifiers, although comments may contain just about anything.

That's implementation- and locale-dependent.  In the default ("C")
locale, only 'a' through 'z' are mapped into different characters by
toupper().
