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.

首先通过 solid.community/account/delete 或 inrupt.net/account/delete 的账户删除表单重现该故障，然后跟踪提交的 WebID 是如何被处理的。将其与注册验证进行比较。当无效的 WebID 不再导致删除请求失败，并且注册行为已得到适当处理时，即视为完成。
