Hi all,

If the .bib file includes a article with Chinese title, I found the
article's length should be equal or less than 22 characters. Once the length
is over 22 characters, the compile process will hang.

The following is an example:

%% filename: test.tex, it depends on the AdobeSongStd-Light.otf font.

\starttypescript[serif][zhfont]
\definefontsynonym[Serif][name:adobesongstd]
\definefontsynonym[SerifItalic][name:adobesongstd]
\stoptypescript

\starttypescript[myfonts]
\definetypeface[myfonts][rm][serif][zhfont]
\stoptypescript

\usetypescript[myfonts]
\setupbodyfont[myfonts,rm,11pt]

\setupbibtex[database=ref]

\starttext

测试\cite[测试]。

\placepublications

\stoptext


%% filename: ref.bib

@book{测试,
  title     = {〇一二三四五六七八九〇一二三四五六七八九〇一二},
  author    = {一二三},
  publisher = {四五六},
  year      = {2000},
}


After compiling the above test.tex, I can get the following test.bbl file:

\setuppublicationlist[samplesize={一00},totalnumber=1]

\startpublication[k=测试,t=book,
a={{一二三}},y=2000,
n=1,s=一00]
\author[]{}[]{}{一二三}
\pubyear{2000}
\title{〇一二三四五六七八九〇一二三四五六七八九〇一二}
\pubname{四五六}
\stoppublication


If I modify the ref.bib file, for example I add one Chinese character in the
"title" field:

%% filename: ref.bib

@book{测试,
  title     = {〇一二三四五六七八九〇一二三四五六七八九〇一二三},
  author    = {一二三},
  publisher = {四五六},
  year      = {2000},
}

When I compile the test.tex again, the compiling process stops here:

publications    : loading database from test.bbl
(test.bbl
! String contains an invalid utf-8 sequence.
l.8 ...�九〇一二三四五六七八九〇一二
                                                  ��%
?

I'm sure that all texts in my files are encoded with utf-8.
