Hi, it seems that st does some terminal codes abnormally[1].
What is the reason for st's key codes to be different from the other
terminals? Is st following some standards?

Yes, st follows terminfo(5). Every terminal has different keys,
so, I don't know what you mean with st using different keys.
You can see the differences between xterm an linux vt:
$ infocmp xterm linux
comparing xterm to linux.
comparing booleans.
ccc: F:T.
eo: F:T.
km: T:F.
mc5i: T:F.
npc: T:F.
xon: F:T.
comparing numbers.
cols: 80, NULL.
lines: 24, NULL.
ncv: NULL, 18.
comparing strings.

How do you know that smkx should be '\E[?1h\E='? Is there any
documentation about it?
If your program does not use terminfo(3)
(http://linux.die.net/man/3/setupterm), then is broken.
About the problems with DELETE, please take a look to
the FAQ (section Why doesn't the Del key work in some programs?)
I had read the FAQ again and again, but I just doesn't understand why some
applications
doesn't work in st but works in other terminal, the FAQ just says that
the applications are buggy.
Good luck and have a nice day!
