Well, the pages about SET-MACRO-CHARACTER and
SET-DISPATCH-MACRO-CHARACTER don't mention any restriction, so any
character is game for macro character.

Read the non-dictionnary parts to get background information, and use
the _permuted_ _index_ to find all the relevant symbols:

  http://www.lispworks.com/documentation/HyperSpec/Front/X_Symbol.htm

Here you could have found all the symbols containing CHARACTER and all
the symbols containing MACRO, and therefore all the symbols about
MACRO-CHARACTERs.  Reading all these pages would let you know that you
can override any character macro.
