This distinction is rarely important,\nbut when it is, the code should use the EscapedPath method, which preserves\nthe original encoding of Path.\n\nThe RawPath field is an optional field which is only set when the default\nencoding of Path is different from the escaped path. See the EscapedPath method\nfor more details.\n\nURL's String method uses the EscapedPath method to obtain the path.",
