Write the specified `filler` (possibly a multi‐byte unicode sequence) to the specified `out` the specified `padWidth` times and return the new output iterator. If `padWidth < 0`, no output is done. The behavior is undefined unless the character type of `filler` is the same as `t_CHAR` or `filler` is entirely ascii. Note that the overloads that input a single character have an advantage over `bsl::fill_n` in that they will automatically widen or narrow the input character to `t_CHAR` if necessary.
