I just found this in the manual:
$ gpg --list-options show-sig-subpackets --with-colons --list-sigs KEYID
And I see for my own self signature:
Referring to RFC 4880, subpacket 11 is preferred symmetric algorithms,
for example. But you need to parse the quoted octets that follow it. For
subpacket 11, this is rather trivial, since %07%09%08%03%02 just means
"S7 S9 S8 S3 S2" as preference string (each octet a symmetric algorithm
If you look at other strings, I see %ACF%EF... at subpacket 16, which is
a nice tricky example where the second octet appears to be 46 hex, ASCII
F. Since 16 is the issuer, it's no surprise the string expands to
AC46EFE6DE500B3E in hex, my long key id.
