Account deletion error with invalid WebID

I just tried removing an account for someone that wanted his account deleted using the delete request form: https://solid.community/account/delete (also occurs on https://inrupt.net/account/delete)

However, when submitting the form, I get the following error (changed the name for privacy reasons):
Error: Error: NamedNode IRI "https://rubentaelman.inrupt.net/Ruben Taelman" must not contain unencoded spaces.

I'm not sure what causes this error. But I think the user may have entered an invalid WebID URI during registration. If that is true, then validation should actually also happen during registration, but more importantly, the deletion request should not fail with such an invalid URI.

Comece reproduzindo a falha pelo formulário de exclusão de conta em solid.community/account/delete ou inrupt.net/account/delete e, em seguida, rastreie como o WebID enviado é tratado. Compare isso com a validação do registro. Considera-se concluído quando um WebID inválido não fizer mais com que a solicitação de exclusão falhe e o comportamento do registro tiver sido tratado conforme apropriado.
