Dear list, I have the following sample: \starttext \index{tipografía digital} \index{tipografías} \index{idioma+de un pasaje} \index{idioma+del documento} \completeindex \stoptext No matter what language I choose (en, de, nl, es, fr), sorting order is wrong: "tipografía" comes before "tipografías" and "de" comes before "del". I’m afraid this may be a bug introduced in latest beta from 2014.10.22 16:23. Many thanks for your help, Pablo -- http://www.ousia.tk
