Actually, one never NEEDS trigraphs; they're required to be supported as a
convenience when interchanging source code among sites or equipment with
poor support for the C source character set.  However, all conforming
implementations MUST support the full C source character set (as specified
in X3.159-1989 section 2.2.1) in addition to trigraph sequences (2.2.1.1).
