Is this text from the ELisp manual still correct?
Sometimes key sequences are represented as strings. When a string is
a key sequence, string elements in the range 128 to 255 represent meta
characters (which are large integers) rather than character
codes in the range 128 to 255.

Almost: it's only true if the string is unibyte.

That's not what I see:
(multibyte-char-to-unibyte ?\M-a)
=> wrong-type-argument characterp 134217825
What am I missing?

Why do you think this is related to the text you quoted?

The text only talks about what happens if you do
(define-key map "\M-a" 'foo)
Note that "\M-a" is a unibyte string whose first byte is 225.
