\setbreakpoints[compound] with numbers

\setbreakpoints[compound] with numbers

[Denis Maier]

Hi,

In the texts I'm currently typesetting, I occassionaly have to deal with 
ISBNs. So, e.g. 978-3-123456-78-9

\setbreakpoints[compound] does not enable automatic linebreaks after or 
before the hyphens. Is there a way to deal with this? Perhaps something 
similar like \hyphenatedurl{} or an extended version of \setbreakpoints.

(I currently use zero-width spaces, so I got rid of ISBNs in the 
margins, but a more automatic solution would be great.)

Best,
Denis

\unexpanded\def\isbnnumber#1%
   {\cldcontext{string.gsub("#1","-","\\automaticdiscretionary")}}

\hsize 1mm \isbnnumber{123-456}
