extraParams in livetable

If value1 is a page reference, and that page reference contains a dot (which is escaped with a backslash => “\.”), this extraParams option does not select the page.
If the page reference contains an ampersand “&”, I can rewrite value1 with the $escapetool.url() function which converts “&” to “#26”. But this is not a solution when the strings contains “\.”
Suggestions?
