The question is ill-formed. Are you asking about allowed characters
in some field of the underlying canonical ASN.1 DER form of a
certificate, or about some particular encoding of the certificate
If the former, X.509v3 certificates are complicated objects, which
part of the certificate are you asking about?
As for keys, in their ASN.1 DER encoding they are "binary" data,
and all octets are a priori valid in a public key. A public key
algorithm that prohibits 0x22 seems unlikely.
