It depends on what you mean.

Registrars could and did allow users to enter in labels for registration
that would end up getting remapped to other labels before registration. That
is, they could let people enter in faß.de <> or Ö, even
though what was actually registered as far as the DNS is concerned was and (=ö <>), resp.

What was unfortunate is that apparently not all registrars made it clear to
the registrants exactly what was being registered.

They should never have allowed (I don't know whether any did or not)
registering punycode that was illegal, like xn--a.
