      Certain characters are treated specially when parsing and interpreting URIs. However, in the
      case where a URI input for `append_to_uri_path` is simply a POSIX path, these characters should
      not receive special treatment. This test case verifies that `append_to_uri_path` properly joins
      POSIX paths containing these characters.
