Hi,

I have a document where I use font expansion to get better line breaks but as a result the spacing between the letters is completely messed up in some words.

\definefontfeature [default] [default] [expansion=quality]

\setupbodyfont [lucidaot]

\setupalign [hz]

\starttext

\dorecurse{20}{appeared }

\dorecurse{20}{around }

\dorecurse{20}{accompanying }

\stoptext

Wolfgang I think this is a side effect of the font design. Lucida has no kerns which means that the boundingbox has to do the trick of kerning. Now, if you look at the 'a' and 'r' you will notice that the right bounds of the a and left bounds of the r are more of less touching the shape. So, when we expand the shape that touching stays and becomes quite visible compared to the far from touching other shape.s

Of course I can be looking at the wrong aspect but then i need an example exposing it. I'll send you some (lmtx) tweak to play with.
