> there's a hard constraint of one key combo -> one Unicode character, which makes it impossible to output multiple characters. The orthodox solution for this problem is an IME. Quickest path to success is via editing a new map file /usr/share/m17n/lut.mim (see Blackfoot and Inuktitut in the same directory for examples of multiple character output) and then using the m17n plugin for fcitx or scim or ibus.
