Trigraphs in C were always hilarious. I've literally seen ø in the source code where { should be (Swedish locale), and ¥ in the source code where \ should be (Japanese code page). The very programmers who should have been affected by having no \ or { in their national character set just typed the character with the same byte code (often, same key). The compiler just read bytes and didn't give a shit what the locale was. Everyone just got on with their programming.

#C23 removes #trigraphs.

So now you really need modern keyboards including # and \ and fancy brackets like [{}], and we cannot use #EBCDIC as source file encoding …
