**NOTE:** The third argument should be a single `char`. However the module doesn't throw an error if you supply more than one `char`s. See [#28](https://github.com/stevemao/left-pad/pull/28).
**NOTE:** Characters having code points outside of [BMP plan](https://en.wikipedia.org/wiki/Plane_(Unicode)#Basic_Multilingual_Plane) are considered a two distinct characters. See [#58](https://github.com/stevemao/left-pad/issues/58).
