Actually, I was incorrect. The 'hat' and 'circle' are sm Attributes each in its
own sm node, and using the non-combining values e.g. U+00e5 and U+02da --there
are font metric issues still, but not with combining diacritics (what changing
the font would otherwise resolve).
Rather, issue is with sm variables that will render in italic, but the nodes
for the non-combining diacritics for each of the sm Attributes do not.
You can force centered alignment of the sm nodes by forcing the variable non
italic--done with the 'nitalic' attribute:
nitalic hat %theta nitalic hat %omega newline
nitalic hat a nitalic hat %THETA nitalic hat a newline
nitalic circle %omega nitalic circle %theta newline
nitalic circle a newline
but you loose italic variables, which folks prefer.
=> NEW
bug 101174 is related, but this is a legitimate mishandling of nodes for sm
Attributes.
And should folks wonder, we intentionally avoid using the Unicode combining
diacritics as per bug 66276
