I have letterhead from Japanese companies which
uses this character for telephone numbers and postal
codes. Also have a laminated flyer from perhaps the
1970's which includes this zero character in citation
numbers. Even though Chinese numbering system has
no need of zero, it seems to have some uses for this
character in references. Mostly, though, the current
practice appears to just use western numbers.
This circular stroke does appear as a component of
a few of the CJK characters in plain 2.
