Macro characters used by various libraries:
direct character definition
# dispatch
(Note that the subchar dispatching is done case insensitively, so we list only uppercase letters, but the corresponding lower case letter may be used too (and might be used often for better readability, notably when a numerical argument is present before and after the subchar)).
