There's no way to get the compiler to deduce T, since
the argument types are "const char[...]" and "const wchar_t[...]".
If you want this, you'll have to either overload for pointers or
do something like

template<typename T>
void func_impl(basic_path<T> file);

void func(path  file) { func_impl(file); }
void func(wpath file) { func_impl(file); }
