\setupsynonyms[nomenclature] [criterium=all,location=serried]
when i type in someting like
\nomenclature{A} {Area}
it works.
But if I type
\nomenclature{$\alpha$}{Angle of something}
it fails. The reason may be only text could be used. I found the list is sorted alphabetically. Then if I type a greek letter, the compiler does not konw how to sort it.
