Adapt to C++20 deleted ostream << for sal_Unicode (aka char16_t)

<http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1423r3.html> "char8_t
backward compatibility remediation", as implemented now by <https://gcc.gnu.org/
git/?p=gcc.git;a=commit;h=0c5b35933e5b150df0ab487efb2f11ef5685f713> "libstdc++:
P1423R3 char8_t remediation (2/4)" for -std=c++2a, deletes operator << overloads
that would print an integer rather than a (presumably expected) character.

But in these cases printing an integer is as expected, so add explicit casts.
