enter image description hereI created a bib file for my references. All my references are in english language. My document is in greek-english language. When I add those references at the end of my document all references are there but in greek text . So I changed the language to english before adding the bibliography and the bibliography is now ok but it creates errors such as: ...unavailiable encoding in encoding T1... and at the same time bibliography entry disappeared from table of contents. How can I fix that?

  • Can you also show a short example of a .bib file? I tried your example and after removing \mytitle and adding a bib file of my own, it works fine: greek letters in the body of the file and Latin letters in the references. i.stack.imgur.com/hy2Rj.png – samcarter_is_at_topanswers.xyz Apr 22 '18 at 18:50
  • I add a picture with a few references from my bibfile. – orion13 Apr 22 '18 at 19:07
  • Can you please add them as text? I'd like to test if I can reproduce your problem. – samcarter_is_at_topanswers.xyz Apr 22 '18 at 19:08
  • yes I add it. you can check it – orion13 Apr 22 '18 at 19:24
  • I cannot reproduce the issue. – egreg Apr 22 '18 at 21:45

The only problem I could find in your code was unrelated to the bibliography, but that \addcontentsline{toc}{section}{Βιβλιογραφία} only worked every other compilation - not sure why.

As a workaround I suggest the tocbibind package instead:

\usepackage{cite}
\usepackage[verbose, colorlinks=true, naturalnames=true, linkcolor=blue, 
unicode, bookmarks=true]{hyperref}
\usepackage{caption}
\usepackage{subcaption}
\usepackage{bookmark}

\addto\captionsenglish{\renewcommand{\refname}{\foreignlanguage{greek}{Βιβλιογραφία}}}

\usepackage[nottoc]{tocbibind}

  • that works perfect! thank you! do you know how can I make "references" in greek language in table of contents and in document? – orion13 Apr 22 '18 at 19:50
  • @orion13 Please see my edited answer – samcarter_is_at_topanswers.xyz Apr 22 '18 at 20:08
  • Perfect! but I have another problem, after compiling a few times all references disappeared from the end of the document (and no errors) – orion13 Apr 22 '18 at 20:16
  • @orion13 Can you try to boil your new problem down to a minimal working example with bibliography (MWEB)? – samcarter_is_at_topanswers.xyz Apr 22 '18 at 20:20
  • if I understood correctly, I believe that its the same as your solution. – orion13 Apr 22 '18 at 20:41
