The original (1960s) ASCII character set was 7-bit only.

8-bit variants of ASCII which preserved the 0-127 range and added graphics or
printable characters from 128-255 are called "extended ASCII" and started in the 80s
with such things as IBM code page 437:

Emacs is more convenient to use if a keyboard has a Meta key which sets the high bit.

"M-x" is how Meta + x is documented per Emacs conventions, but Esc + x is an alternative
for keyboards which do not provide a Meta key.
