Is it possible to encode (in some existing program) for letter pairs where each code point is the right-hand side of the first letter of the pair plus the left-hand side of the second letter in the pair ? I ask because upper-case Finnish has lots of really gnarly whitespace/kerning issues. Letter pairs like LJ and KY and YT and VY that could get special attention, even stroke joining, in a font such as I describe. So a fragment like " KEVYT." could be encoded as (spc + lh-K), (rh-K + lh-E), (rh-E + lh-V), (rh-V + lh-Y), (rh-Y + lh-T), (rh-T + period).
