Of course not, or maybe yes, but limited to numbers from 1 up to 12,
via a proper mapping file. However, with the macros I gave you before,
you can define

\makeatletter
\newcommand\ordinal[1]{\@UniRoman{#1}}
\makeatother

and write "Henri~\ordinal{4}". The tilde is for avoiding a line break. This will
use the character corresponding to the number, if in the range 1–12, otherwise
the number will be constructed from the Roman numerals.

Ciao
Enrico
