I've given the solution an attempt:
https://github.com/haasn/libplacebo/commit/0e67eec23628f97089bb25724248e502694c57bb

This works on my end, but currently only has an implementation for
systems with `uselocale`, which apparently Win32 does not belong to. On
Win32, there are locale-invariant versions of printf which could be used
to implement the same API, but I'm unable to produce this code. (BSD
could also use the printf_l etc. wrappers, although BSD supports
uselocale so it shouldn't be necessary)
