A few weeks ago, I asked for the best method to prevent a ligature while
allowing hyphenation at this point as well as before and after in the same
word. (like "| which german latex users will probably know)
At the end, Hans gave me this:
\definetextmodediscretionary *
{\prewordbreak\discretionary{-}{}{\kern.05em}\postwordbreak}
\startlanguagespecifics[de]
\installcompoundcharacter "| {|*|}
\stoplanguagespecifics
I was pleased and started using it, but now I noticed a problem. If you say
e.g. Auf"|lage, there can be a line break after 'Auf' without hyphen. The
reason became clear after having a look at supp-lan.tex and the texbook.
The above definition is equivalent to
\definetextmodediscretionary *
{\penalty10000\hskip0pt\relax
\discretionary{-}{}{\kern.05em}%
\penalty0\penalty10000\hskip0pt\relax}
So, there can be a line break at \penalty0, in which case there will be no
hyphen dash and the kern will disappear. So, for those interested, I would
propose
\definetextmodediscretionary *
{\prewordbreak\discretionary{-}{}{\kern.05em}\prewordbreak}
