^^^^^^^^^^^^^^^^^^^^^
[1]'ISO/IEC 9899:1999 Programming languages -- C' says in §5.2.1.1 that
C trigraph sequences are:
??= # ??) ] ??! |
??( [ ??' ^ ??> }
??/ \ ??< { ??- ~
"No other trigraph sequences exist", I didn't look [2] 'Corrigendum 1,
ISO/IEC 9899:1999/Cor 1:2001', but I think that they were not modified.
And inside of comments there are not trigraph substitutions, at least
in theory §6.4.9.
I only found a few in 2.4.22-bk30, aka 2.4.23-pre7:
