Is there any possible way to automatically escape characters when executing an alias in zsh?

[Steve Dondley <s@xxxxxxxxxxx>]

I have many aliases set up for taskwarrior in zsh:

alias tasn="task +sn add"`

On the command line, I'll type in:

tasn some task description here

Which works unless I put in single quote or some other character:

tasn call Tom's friend

This will thrown an error unless I escape the apostrophe.

I don't want to turn these into functions because then I lose the 
autocomplete capabilities. I'm wondering if there might be some neat 
trick that will allow me to automatically escape apostrophes (and other 
problematic characters) in the task description.

Thanks.
