That part is defined by filesystem::path - character code conversion
happens. What isn't clear in the code Vinnie posted earlier is what is
supposed to be appended (percent-escaped string or not) and how (path
appending or dumb concatenation). That's the problem with the docs, it
says "appends", but there are too many ways to "append".
