[Doc-SIG] Unicode Charent Substitutions

[David Priest]

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!).
