Experiment doesn't work with pipe character in URL query

[analytics_union]

I have an audience as shown in this screenshot:

But when I open a link like www.foo.com?cmp=baz|trt|meg, my experiment doesn’t run.

If I open www.foo.com?cmp=baz%7Ctrt%7Cmeg, then my experiment runs as expected.

Does anyone know why using "|" doesn't work even though I've setup the audience as shown?

Try to commenting out those | symbols. Instead of querry contains = |trt| try querry contains = %7Ctrt%7C

That's what I had put in my Audience definition. See the "Or" conditions in my screenshot.
