The C standard says that C uses ASCII, regardless of what character set
encoding the underlying system uses.
 
So:
 putchar(0x21) always emits a pling,
 putchar(0x30) always emits a zero,
 putchar(0x41) always emits the system's representation
               of an upper case 'A'
 putchar(0x61) always emits the system's representation
               of a lower case 'A'.
 
For example, if you had a C compiler for the ZX80, then
 putchar(0x30) when sent to the screen would send 0x00
 to the screen drivers.
 
If you were using a system that used EBCDIC, then
 putchar(0x30) would send 0xF0.
