A quick search at Google reveals that the mentioned (MC) and (MD) in fact are
written by raised letters without parens, thus resembling the English ™.
If this is correct, these combinations have a distinctive semantic value and
must be enabled to be written in plain text.
Thus, I disagree with Kenneth Whistler's conclusion that there is no
need for a new encoding, as raising the letters by a higher level
protocol is not applicable in all circumstances.
While it is possible two new symbols like the existing ™, this in fact
does not seem to be the most desirable way, as then possibly a lot of such
combinations which are used in other countries also have to be encoded.
Thus, it seems to be appropriate to use modifier letters (i.e. raised
letters encoded in Unicode mainly as phonetic letters ore as constituents
of special orthographies.)
The following letters already are encoded:
U+1D30 MODIFIER LETTER CAPITAL D
U+1D39 MODIFIER LETTER CAPITAL M
Thus, missing for your purpose is a MODIFIER LETTER CAPITAL C.
If you submit a formal proposal for this letter (which you can do
individually, but which has more chances to succeed if an official
French organization will submit it), the Unicode Committee and the
appropriate ISO committee (SC2/WG2) will decide about it.
