@eggrobin I changed the consensus number from C34 to C33. Apparently there is an off-by-one thing between your count and Rick's minutes.

[asmusf]

I'm having second thoughts on making the MEDIUM WHITE CIRCLE WITH HORIZONTAL BAR an "Sm" in General category.

Double checked and most of the other geometric shape inspired ones are So.

As there are potentially generic uses, I'm not as comfortable with the Sm; I thought there were clear analogs, but now I can't find any. Unlike for the arrows where Sm would be consistent.

changes lgtm

Re Asmus’ concern: The new small circle with bar U+2B96 is mentioned in both the proposal and in https://github.com/unicode-org/sah/issues/323 as related to the larger U+29B5 which has gc=Sm.

name fix lgtm tnx

I see you are rubberstamping these faster than I can ask you to!
