Two remarks:

1. The zero implicitly added to literals is not part of the 
string. for example s[$-1] will not give 0 unless you added it 
explictly to a literal

2. you code remove all the 0, not the one at the end. As it still 
ensure what you want to achieve, maybe try 
[`stripRight()`](https://dlang.org/phobos/std_string.html#.stripRight). The second overload allows to specify the characters to remove.
