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. -- Best regards, Li Yanrui
