So it fails in any case of nonbreakable text.
How about adding a failsafe test ala
\ifdim\dimexpr\wd\plusone+\wd of sentinel\relax>#2\relax
\clip[width=\wd\plusone,...]{...#1...}\removeunwantedspaced#3%
\else
\box\plusone\removeunwantedspaces#3%
\fi
One (ugly looking) partial character is still better than a bunch of
characters, that cross the width border.
I have played around with \clip, but it acts a little wild (vertical
position and height). Can't subdue it myself...
Greetings,
Peter
