Hello Alan, I have tried the solution you have suggested, nevertheless it does not affect the position of letter 'Ch' in the list of publications. Setting the \mainlanguage[cz] affects for example format of \date, but not the alphabetical order of bibliography. I have tried switching to other languages like fr, de, nl and none of them had any effect on the sorting. Commands \setupdelimitedtext[language=cz] and \setupbtxdataset [language=cz] do not have any effect either. Is there any way how to change the alphabet sequence of specific language, in this case of Czech? It seems like Ch is hardcoded to preceed C and Č. I suspect this may be also the case of other alphabets. Thank you, Petra On 8 February 2017 at 17:08, Alan Braslau wrote:

Hello,

I believed that the sorting order follows the current active language (\mainlanguage[cz]).

You might want to try \setupbtxdataset [language=cz] but I have never used this (I believe that it sets the default language for entries lacking a language= field).

Sorting can be controlled as follows: \startsection [title=Bibliografie] \setupdelimitedtext [language=cz] \placelistofpublications \stopsection

This is useful for multilingual documents.

Other settings for \setupdelimitedtext [language=...] are <blank> (the default, use the current active language) local (respect the local language directives, i.e. the bibtex entry field language=) global (impose the main document language) en, de, nl, ...

Hello,

I am fairly new to the ConTeXt community and I am trying to sort bibliographical references for my thesis. I need to be able to set the sorting order of the bibliographical references by Czech alphabet (e.g., C,Č,D,....Ch,...etc.). English sorting puts Ch before C or Č, but in Czech it needs to be after D. Any ideas?

http://tex.stackexchange.com/questions/352496/bibliography- sorting-order-by-czech-alphabet-in-context/352514#352514

Here is the minimal example

\mainlanguage[cz]

\usebtxdataset[bibliotest.bib] \usebtxdefinitions[apa]

\unprotect %here I substitute the annoying ampersand with czech a \def\textampersand{a} \protect

\setupbtx [apa:cite] [left=, right=, separator:2={\btxsemicolon}, % :0 and :1 - between items of a list separator:3={\btxsemicolon}, separator:4={\btxsemicolon}, separator:names:2={\btxcomma}, separator:names:3={\btxcomma}, separator:names:4={\btxcomma}, etaldisplay=3, etallimit=3 ]

\starttext

\cite[righttext={{123},{116-156}}][Danton2004, Cicikova2011].

\cite[Cicikova2011]

\cite[Chichikova1978]

\startchapter[title=Bibliografie] \placelistofpublications \stopchapter \stoptext

and the database bibliotest.bib

@book{Danton2004, address = {Oxford}, author = {Danton, Gocha R. and {De Angelis}, Franco}, publisher = {Oxford University School of Archaeology}, title = {{The archaeology of Greek colonisation: essays dedicated to Sir John Boardman}}, year = {2004} }

Thanks in advance,
