**Description** In #67 we added tests about the url encoding of user info fields. However, in the [discussion to define the expected behaviour](https://github.com/php-fig/fig-standards/pull/1298) in PSR-7, the concern has been raised that there can be unclear cases where some characters look like url encoded and others are not encoded **Example** Should the `%` in `pa%65sw:ord` be encoded? Most likely yes, but there is disagreement in the discussion on the PSR-7 what to do in such a case.
