Many Thanks Hans!

But that's not exactly what I need, sorry for being imprecise, I do
not need to repeat hyphens, but only  em dashes (or en dashes, which
ever are used in the document) in situations like this.

Most newspapers — and all that follow AP style — insert a space before
and after the em dash.

It should look like this:

\starttext

\def\LEFT {\space\emdash\nbsp}
\def\RIGHT{\nbsp\discretionary{\emdash}{\emdash}{\emdash}\nbsp}

\setuplayout[width=21mm]
\setuplayout[width=24mm]

\setuptolerance[verytolerant]

\showframe

test test \LEFT a test and some more test\RIGHT\ test test

\stoptext


All Best

Hello list,

This is probably a Polish idiosyncrasy, but we have to live with it.
According to punctuation rules when an em dash is at the end of a
line, it should be repeated at the beginning of the next one (true, it
is often disregarded due to lack of support for it in typesetting
programs). Is there any way to deal with it in ConTeX?


\starttext

     \setuplanguage[pl][lefthyphenchar=45,righthyphenchar=45]

     \pl \input tufte

\stoptext
