Comment (by simjost):

 Hi @TimothyBlynJacobs,

 I have no definitive proof, that pipes are allowed. When checking and
 searching, I read that they were forbidden some time ago and it's still
 not suggested to use them. But I didn't check any further.
 If possible I avoid them of course :)

 Alright, so the issue happens during a canonical redirect. I still think
 the pipe should not just disappear. Either it stays or it gets encoded,
 like on the base url.
