 The concept of "valid UTF-8" used is perl's concept, which is a superset
 of the official UTF-8.
 If C<$enable> is false (the default), then C<decode> will blindly accept
 UTF-8 data, marking them as valid UTF-8 in the resulting data structure

+regardless of whether that's true or not.
 Perl isn't too happy about corrupted UTF-8 in strings, but should
 generally not crash or do similarly evil things. Extensions might be not
 so forgiving, so it's recommended to turn on this setting if you receive
 untrusted CBOR.
 =item hash references
 Perl hash references become CBOR maps. As there is no inherent ordering in
 hash keys (or CBOR maps), they will usually be encoded in a pseudo-random
-order. This order can be different each time a hahs is encoded.

 Currently, tied hashes will use the indefinite-length format, while normal

 serialisation protocol). See L<OBJECT SERIALISATION> for details.

 generated in Perl with some effort, they were considered too unimportant
