That is the question I answered -- in full generality.
Instead of sending you a very long list of replacements,
I sent simple general rules to handle ALL characters
that have the form LETTER + DIACRITIC, and ALL characters
that have the form LETTER + DIACRITIC1 + DIACRITIC2.
The character you just cited is LATIN SMALL LETTER A WITH BREVE AND TILDE.
The rule is
For each character whose name has the form
latin (small|capital) letter \1 with \2 and \3
if the terminal can't display that, but it can display \1 with \2,
it should display
LATIN (SMALL|CAPITAL) LETTER \1 WITH \2
followed by the graphical form of \3.
Otherwise, it should display
\1 followed by the graphical form of \2 followed by the graphical form of
\3.
Following this rule, Emacs would display ă~, if the terminal can handle that,
otherwise a˘~ .
Have I said it clearly this time?
