Hi, Ben: If the Chinese full stop is an legal character in IDN, it has to be in [nameprep] profile and is equivalented to an ASCII dot. If IDNA only deals with a label, that is a string of LDH, between dot/slash/!/#/@/% and whatever, then the Chinese full stop will function as a key element to flag a label. So, if such an flag appears within a label, then one label becomes two labels, ie. <zhongguo>.com becomes <zhong>.<guo>.com, we have trouble.
When we deal with TC/SC for a IDN label, the punctuations have to be excluded. But about circled characters, they have similar processing property with Latin letters which have diacritic marks on them, where the only differences is circled characters in UCS mostly CJK characters, and CJK characters are taboo to talk about in many WG members' mind.
