Indeed, PostScript does not support Unicode, though for the
characters which it does support it would be possible to
convert Unicode into appropriate PostScript references.

However, PostScript does have a centred (non-superscript)
asterisk. This is in the "Symbol" character set, and it is
called "asteriskmath", with octal code 052 (decimal 42).

But I do now know how to instruct R to cause this to be printed!
(Though I feel sure someone else does).
