Hi, list! Lou_checkhyphens works now. I did './substrings.pl /home/lrs/tmp/liblouis/tables/hyph_nb_NO.dic t.dic ISO8859-1 2 2' Trying to run no-no-g0.utb,t.dic through lou_checkhyphens, gives some more hyphens than the original one (liblouis/tables/hyph_nb_NO.dic). But, as I used 2 as the last two parameters to substring.pl, I expected that shorter words, like "ikke" should return "ik-ke". That word is not hyphenated. Also, I would expect lou_checkhyphens to return all permitted hyphenation points. Until now, I have only found one dash per word. Do I missunderstand something?
