strip only removes whitespace, not null characters. You'd have to 
do something like
```d string t = cast(string)text("head-", s, "-tail").filter!`a 
!= '\0'`().array;```
I would assume there would be a better way, but I haven't been 
able to find a dedicated function for stripping null chars in std.
