Actually, this bug had the nice side-effect of identiying a few spots in  
this huge project (journal) where the conversion of articles to context  
was buggy (like that u-2011 example, they were all supposed to be  
converted). Nice to get a _helpful_ bug for a change. OTOH that should be  
fixed anyway...

The interesting thing is that using the default lm setup it does not show  
up, but as soon as font features are activated it does.

No. You get that error because the font does not have a non-breaking 
hyphen, and you can "fix" it by changing that line into

   if characters[current.char] and  characters[current.char].class == 
"mark" then

and regenerating the format. But it will still not "work", because
the glyph still does not exist.

Best wishes, Taco

Does this handle the other [off-list] utf-8 bug that generates an error  
message from font-tfm.lua:591?


(I sent the wrong test file before, sorry)

hm, you need to to test shared before using it, so it really is:

function fonts.otf.set_dynamics(tfmdata,attribute,features)
local shared = tfmdata.shared
if shared then
   local dynamics = shared.dynamics

i wonder what you tested -)

you forgot "local dynamics", the following works

function fonts.otf.set_dynamics(tfmdata,attribute,features)
local shared = tfmdata.shared
local dynamics = shared.dynamics
if shared then

I have another one.

% engine=luatex

\definefontfeature[texlig][tlig=yes]
\setfontfeature{texlig}

\starttext
--
\stoptext

If I set tlig=no everything works fine, but with tlig=yes I get the
following error message.

error: ...2tex/share/texmf-local/tex/context/base/font-otf.lua:2017:
