I have a recollection of early Netscape versions displaying local file 
paths in the Location bar as something like file:///c|/windows/canyon.mid.

Performing some code archaeology at 
https://mxr.mozilla.org/classic/source/cmd/winfe/fegui.cpp#2531 (note 
line 2359) suggests that I was not hallucinating (there are other places 
in that file where ':' and '|' are treated more or less equivalently in 
file: URLs).

I imagine that it’s an early Netscape implementation detail that escaped 
into the wild. Given that I can still remember pipes in file URLs 15+ 
years later, I would not be surprised if other people rely on this working.
