decode options?

[ToddAndMargo via perl6-users]

Hi All,

Uhhh,

    https://docs.perl6.org/routine/decode

       role Blob

       From Blob
       (Blob) method decode

       Defined as:

       multi method decode(Blob:D: Str:D $encoding = 'UTF-8' --> Str:D)

       Applies an encoding to turn the blob into a Str.

       my Blob $blob = "string".encode('utf-8');
       say $blob.decode('utf-8'); # OUTPUT: «string␤»

       On malformed utf-8 .decode will throw X::AdHoc. To handle
       sloppy utf-8 use utf8-c8.

where are the decode options?  I only see utf-8 and utf8-c8.
Am I blind?


Many thanks,
