Oops, my fault.  The above keysym is returned by typing
"RightAlt-' c".   With just "RightAlt-'", xev reports these
keysyms (the first one by RightAlt, the second by ':

    XLookupString gives 1 bytes: (27) "'"
    XmbLookupString gives 1 bytes: (27) "'"
    XFilterEvent returns: True

Please note that XFilterEvent is True in both cases.  Thus
some input method has filtered them.
