Highway code rule 188:

Depends how you interpret "avoid."  I am not a lawyer.  If I wrote a
router, I'd err on the
side of caution here: don't suggest a U turn as a feasible route, don't
allow a user to enter
a route with such a U turn.

I believe the same would be true for any country.

Countries have their own legislation.  Poland apparently has things that
look like mini
roundabouts but follow the regulations of "ordinary" roundabouts.

Therefore, it is worth knowing whether it is a mini or standard roundabout.
