ConText and bibliography

Question

Trying to compile simple example of using bibliography in ConText (from contextgarden wiki). My file is:

\mainlanguage[russian]
\usemodule[simplefonts][size=12pt]
\setmainfont[XITS]
\setsansfont[Arial]

\setupbibtex[database={mybib},sort=author]
\setuppublications[alternative=apa]

\cite[Tolh]

\completepublications[criterium=all]

\stoptext

Corresponding bib file is:

@Article{Tolh,
  Title                    = {{Поляризация электронов. Теория и эксперимент}},
  Author                   = {Тольхук, Х. А.},
  Journal                  = {УФН},
  Language                 = {russian},
  Year                     = {1957},
  Number                   = {12},
  Pages                    = {761--800},
  Volume                   = {63}
}

Well, it is in Russian, saved as utf8, and the main file is also in uft8. So, compilation with context stops with error:

tex error       > error on line 1 in file 2.bbl: ! String contains an invalid utf-8 sequence

l.1 \setuppublicationlist[samplesize={Т
                                      �57},totalnumber=1]

 1 >>  \setuppublicationlist[samplesize={Т�57},totalnumber=1]
 2     
 3     \startpublication[k=Tolh,t=article,
 4     a={{Тольхук}},y=1957,
 5     n=1,s=Т�57]
 6     \lang{russian}
 7     \artauthor[]{Х.~А.}[�.~�.]{}{Тольхук}
 8     \pubyear{1957}
 9     \arttitle{{Поляризация электронов. Теория и
10       эксперимент}}
11     \journal{УФН}

As I understand, these "black ?" mean some encoding problems. How to resolve them?

Finally, I would have publications be printed in numbered list in the order of citation in main text, and citations are numbers in brackets (i.e. [1], [20] etc.). Just like LaTeX does bibliography. Is it possible with Context?

Answer 1

The old bibliographical system used bibtex, which still relied on ASCII (more or less), that's why your example fails. Context has a new bibliographic system that completely bypasses bibtex; it can do what you want. It's still a bit experimental (and the documentation is not as full as one might wish). Here's your example rewritten:

\mainlanguage[ru]

\setupbodyfont [xits, 30pt]

\usebtxdataset     [mybib]
\usebtxdefinitions [aps]
\setupbtxrendering [default]
                   [numbering=yes]

\starttext

\cite[Tolh]

\placelistofpublications[criterium=all]

\stoptext

I guess that's what you mean. I don't know how LaTeX does bibliography – if this is imperative for you, it might be better to stick with LaTeX.

Result:

To dump a complete list of publications, use:

\usebtxdataset[customname][database.bib]
\definebtxrendering[customname][apa][
  dataset=customname,
  numbering=yes,
]

\starttext
  \startbackmatter
    \startchapter[title=Bibliography]
      \placelistofpublications[customname][method=dataset]
    \stopchapter
  \stopbackmatter
\stoptext
