The intent (to write ideographic zero, not white circle) is quite clear,
because that's what the key "ling2" means in Mandarin. As is usually the
case in Chinese, ling2 can also mean a lot of other things, but white
circle is not one of them.

You can check with any Chinese or Japanese input method what suggestion
you get for that key (in Japanese that'd be れい/rei). I, for example,
use fcitx with mozc for Japanese and sunpinyin for Chinese, both of
which do the right thing. (I don't normally use Emacs input methods for
CJK languages, I find quail too limited for those and I suspect the same
will be the case for other serious users, which might also be the reason
for the lack of previous feedback.)

That said, by all means, do check with Handa-san, I'm kind of curious
myself.
