1721 is not the code of the Greek theta in the Emacs encoding, that's
why it fails.  Try this instead:

    M-: (insert (decode-char 'ucs #x3b8)) RET

Please read the entry in the file etc/PROBLEMS named "Problems when
using Emacs with UTF-8 locales", perhaps the advice there will help
you.

Because Emacs should know how to interpret each code sent by your
keyboard.  If there's a mismatch between what the keyboard sends and
what Emacs knows about that, you will get gibberish in your buffer.
