For example, gcc.dg/ucnid-8.c.  Put -fextended-identifiers in dg-options, 
write code that generates a diagnostic including an identifier containing 
a universal character name and verify that the universal character name 
(in the \Unnnnnnnn form - which requires \\\\U to match it in 
dg-warning/dg-error) appears in the diagnostic rather than the raw UTF-8 
form (given that gcc-dg.exp sets LC_ALL=C so the testsuite runs with the 
C locale).
