Usually I agree, but in this specific case, I prefer to not see "^" and "_".

Here is the scenario:
\int f(x)dx =0

Now TeX-fold-buffer gives:
∫ f(x)dx =0

So the integral is represented by its unicode symbol.
Now I modify the equation

∫ f(x)dx = \sum_{j=1}^{\infty}

Sum is NOT represented this way, however when I run
TeX-fold-clearout-buffer, and then again TeX-fold buffer I obtain:

∫ f(x)dx = ∑_{j=1}^{∞}

Can you reproduce this behavior? Don't you think that it is
