In 2.3.3.4 Meta-Character Syntax of Emacs Lisp Reference, I am not clear with `2**27' . A bit has two states. Does `2**27' mean that there are 27 bits ?
`In a string, the 2**7 bit attached to an ASCII character indicates a
meta character; thus, the meta characters that can fit in a string have codes in the range from 128 to 255, and are the meta versions of the ordinary ASCII characters. '
Does above para mean: 2**7 bit pluses an ASCII character denotes a
meta character ? What does the `string' mean ?
Thanks
