japanese is not yet defined; we need entries in scrp-ini and scrp-cjk 
for that, character categories and initializations and we need japanese 
expertise for that

Japanese is supported (it’s only a few extra chars for the chinese code) and worked till February 2011 and I was no able to narrow it down.

The function scripts.preprocess in scrp-ini.lua has at line 381

                        if originals then c = originals[c] or c end

which change the real character value to 65533 (REPLACEMENT CHARACTER), when i comment the line there is a line break (see attachment).

you can comment

          -- if not unicode then
          --     originals[index], tounicode[index] = 0xFFFD, "FFFD"
          -- end

in font-map.lua (delete the cache of jump the otf version number)

but nevertheless we probably need to add some mappings if we want to 
treat japanese, like

--  for i=0x03041,0x030FF do if not hash[i] then hash[i] = "japanese" 
   end end

etc
