> Hi, Marshall.
> I've started implementing and testing `to_string` via `to_chars` and realized that `to_chars` doesn't support `wchar_t` unlike `to_wstring`.
> I'm going to extend `__to_chars_itoa` implementation in order to support `wchar_t` and reuse those internal template function.
> Could you please confirm that this way is ok in order not to through away the third attempt on completion.
I would just use `to_chars` to make a narrow result and then widen it.
