I don't think this is the answer either. The plain answer to the
question in the subject line is "No". Unicode does not have these
two characters (dozenal digit 10 {a turned digit 2} and dozenal
digit 11 [a reversed digit 3}).

From the point of view of character encoding, I don't think it would
be correct to substitute out either the A/B usage (from hexadecimal
implementations) or the Roman numeral characters, although it is
easy to see how one could implement dozenal numerical formatting
with either (or for that matter, using "t" for ten and "e" for
eleven: 1 2 3 4 5 6 7 8 9 t e 10 11 ... 19 1t 1e 20 ... etc. or
any other arbitrary choice of characters.

But if the Dozenal Society of Great Britain feels that its particular
usage of characters is important, then they (or anyone wishing to
sponsor their usage) could submit the appropriate Summary Proposal
Form for encoding characters to UTC and WG2 for consideration.

If these two characters pass a threshold test for being more than
idiosyncratic usage characters, then I am sure that in due time they
could be included in the Unicode repertoire.
