The IM framework's response to this challenge is twofold:

  . typing characters that could be part of a recognized input
    sequence shows in the echo area the candidates for the next
    character;
  . C-h C-\ RET shows the full chart of the supported sequences and
    the corresponding characters.

The latter possibility is a close equivalent of "C-x 8 RET" for the
case that the use doesn't know the name of the symbol even
approximately.  (In the "C-x 8 RET" case, the user would just type
"C-x 8 RET TAB" to get the list of possible completions.)
