 Back in the early days of C standardization ('89), trigraphs were supported
to handle characters missing from the compiler character set.
 Specifically to handle the braces (??< and ??>).

That friend  said that around 1983. About the Apple II (released 1978)
The Apple II had no | or \ or { or } or even [ or ]  on the keycaps. Nor _ or ~
These were added for the Apple III. I have no idea whether they were  in fact able to display  them or to enter them via some obscure sequence of keystrokes, but it wasn't a simple process.
The easy way would be to use a generate a macro file like
printf("#define BEGIN %c\n", 123 );
...and so on to bootstrap being able to write the code using what keyboard input you had.
Looking back, it seems unlikely that any programming language apart from BASIC or ASSEMBLER would be possible.
There were compilers for 6502s  but the rather large runtime libraries made them a poor choice for small memory machines. BASIC was in ROM and ASSEMBLER only used what you wanted it to use
Personally I thought the Apple II was a rich boy's toy.
Come to think of it, that sums up nearly every apple product..
