Could you copy/paste the link text of the link that doesn't work for you? All of the links in the post work for me in Firefox (Win 8 / desktop--haven't tried mobile).

tl;dr The %20 stuff in the sample support request is how browsers interpret a space in a URL. I recognize "%7C" as being | ("pipe" in English) because it's also the Unicode designation: U+7C = | (|). It looks garbled but holds meaning for computers.
