No, they aren't. Unicode encodes the same characters encoded by ASCII (at
the same code points) and the same characters encoded by JIS (at different
code points), but it does NOT(*) include the ASCII or JIS code points
themselves. That would be like assigning a code to represent a code which
represents a character.

(*: Actually, 33 ASCII code points are encoded in range U+2400..U+2422, to
allow visible symbols for ASCII control codes).

Encoding the navy's flag alphabet or the Morse code would be exactly doing
this: assigning a code to a code which represents a letter.

But such a thing actually has a precedent: the Braille block. But this had a
(faint!) justification: those Braille patterns are not used to "encode
Braille in Unicode", but rather to encode commands to be sent to Braille
printers ("embossers", actually).
