Autocomplete: Can I change source separator from comma?

Autocomplete: Can I change source separator from comma?

Sorry if this is a dumb question but I'm still very new to this.

I'm using an Autocomplete field and having a problem that I think is because some of the items on my source list have commas in them. I was wondering if there is a way to change the input separator from a comma to something else?

Thanks for any help.

Example of what I mean (it's not for addresses really)...

$('.selector').autocomplete({ source: ["4 Somewhere Rd, Somewhere", "6 Elsewhere Avenue, Elsewhere"] });
