\a \copyright
\quad
% Argument of the accent can contain an expandable command (including
% an active character) only as a first token.  But even then, it's
% best if it's the only token in the argument, because |\bf a| and
% |\bfa| will not be distinguished by the cache.

\msg{Composites}
\'e
\'g
\quad
% Improperly defined composite -- |\a e| does not restore the original
% encoding before calling another glyph macro (|\'e|), which results
% in |e| being typeset in the encoding of the |\a e| composite (OT1).
\a e
\a g
% Now the original encoding is properly restored -- therefore |\'e|
% is called from T1; since T1 contains the composite |\'e|, we get
% that.  For |\'g| we get an accent since there's no such composite.
\a E
\a G
\quad
% A more complex example with the actual accent coming from yet
% another encoding.
\a m
\a M
\quad
% And now even the accent's argument is from a different encoding.
