I'm not sure what consistency you have in mind.

We use the data in the Unicode file EastAsianWidth.txt to determine
which characters should have a char-width of 2.  The characters you
mention are not East-Asian characters, and therefore do not get 2 as
their width.  And at least some of them, e.g. U+1F5A0, are of the same
width on my screen as Latin letters, so 2 would be wrong for them.

Can you tell what practical problem in Emacs are you trying to solve?
