Is there $L$ such that $L$ and $\bar L$ are context free, but $L$ is not deterministic context free?

Question

The usual candidates for context free languages whose complement is also context free, but they are not regular are the Deterministic Context Free Languages ($DCFL$).

For example, $L=\{a^nb^n\mid n\in\mathbb N\}$ is such language.

Is there a language, $L\in CFL\setminus DCFL$ such that $\bar L\in CFL$?

---

Since $DCFL$ is closed under complement, this is equivalent of asking whether $$CFL\cap co\text{-}CFL = DCFL$$

Answer 1

See here:

For every finite, non-unary alphabet, the language of all palindromes is not in DCFL, but in the intersection of coCFL and CFL.
