So, this:




\hsize 1mm


results in



with proper kerning and ligatures when applicable and

wis-kun-d{e-}{o}{eo}(e\zwj o)n-der-wijs

will do the same but no compound dash. It's actually mostly a matter of 
communicating with the font handler (without hard coding solutions in 
the engine).

As a side effect (teaser) you can do this in the upcoming lmtx:


{\myfont               test effe every}\quad
{                      test effe every}\par
{\myfont \nokerning    test effe every}\quad
{        \nokerning    test effe every}\par
{\myfont \noligaturing test effe every}\quad
{        \noligaturing test effe every}\par
{\myfont               test effe e{\nokerning v}ery}\quad
{                      test effe e{\nokerning v}ery}\par

with \nokerning and \noligaturing being macros that set some options 
(the old \noligs and \nokerns have therefore been dropped) ... so one 
has local control over matters (base mode and node mode).

one can even control left/right kerning/ligaturing this way but that's 
something to be explained in some article or at some user meeting or so 
(after all i occasionally need something new to tell)

so, in the end all you have to do is come up with a list of exceptions
