Sorry, somehow I misremembered and thought the character was a with
macron and tilde.  Was it actually a with breve and tilde?

Then the natural visual representations would be ă~ (a with breve,
then tilde) and ã˘ (a with tilde, then breve),

Since the linux console does handle many modified letters, a display method
that taks advantage of them will be good on linux consoles.

At least, on my machine it does that.  I don't know how much variation
there is or how much this can be configured.  I can try to find someone
who knows.

It is much better.

I would never hae guessed what a(? meant, just from seeing it.
ă~ I could guess -- it's an a, with a breve and a tilde.
Once I know it's a single character, because C-f moves over it,
it would have to be a-with-breve-and-tilde.
