Not important. Would you like me to change it?

I think we should. Now we need to select a meaningless character... I took the list that appears in https://tools.ietf.org/html/rfc3986#appendix-D.2 and looked for a nice character that we could use as a separator.

(the pipe) is about the best that I can do. Next up is to verify that this character is safe in each of our backing stores. Then I shall make the change. Any opinions?
