Without seeing how you use it, I can't tell you if it's wrong
or not.
If you want to have a look the original C-library is here

I'm only using the encoder function iec16022ecc200f.
If it's a literal, you don't need to toStringz (which also
allocates). All string literals are zero-terminated (and
actually implicitly castable to `immutable char *`).

Thanks, I'm just careful with casting.
Does it really allocate from a literal if it's used on the stack
only? Is `-vgc` switch reliable?
