The Unicode "charent" substitions file is available at http://www.sfu.ca/~priest/ReST_Unicode_Substitutions.txt It contains |substitutions| for various mathematical, Greek, punctuation, and miscellaneous symbols. It requires the latest DocUtils beta, which supports the use of upper-and lower-case distinctive names in a substitution (ie. |Alpha| and |alpha| are different substitutions). You'll frequently need to use the disappearing-space escape convention to use these substitutions correctly, ie.) "100\ |deg|\ C" to create 100°C (I think!).
