Looking at your code, I think you'll find this is because you're using
echo without the option not to expand bacslashes.  Try "echo -E" or
"print -r".  (I'd recommend "print" if this is zsh-specific as echo
is mostly there for backward compatibility, although there's no reason
it shouldn't work here.)
