Import values to List Box Field type

I want to Import a csv. that has multiple values for List Box Field type.
I tried using a coma to separate the values, but that did work.
What is the proper separator for multiple values in a List Box field type?

Well, a comma is but when the field separator is also a comma, that kinda messes with it.

Can you save it using the pipe (’|’) symbol as the field separator? Not sure if the IS import will pick it up but it is standard with csv files to do that so it may.
