I'm writing a thesis with Texmaker and for my bibliography I work with Mendeley in combination with biber 2.12.

So far, I wrote my text and added a lot of sources with the command \cite{example2019}. example2019 is one of the citation keys in Mendeley.

I have my .bib file from Mendeley and now I started to connect Mendeley with my tex-file with biber.

After running biber (Process exited normally), I get 4 errors form texmaker with the following text:

2 times: ! Package inputenc Error: Unicode character ′ (U+2032)

2 times: ! Package inputenc Error: Unicode character ′ (U+2212)

U+2212 seems to be a minus. However, many of my 300+ sources have a minus.

How can I find the problems most time efficient?

PS: I use the package

\usepackage[utf8]{inputenc}

and I tried to convert the .bib file into utf8 with TextEdit on OS X

  • TeXmaker is a front-end editor, not an engine. Please tell us which TeX engine you use: pdfLaTeX, XeLaTeX, LuaLaTeX, or something else?

  • If you're free to use either XeLaTeX or LuaLaTeX, which are two unicode-aware TeX engines, the issue you're experiencing will take care of itself automatically.

  • I'm using pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2018). I don't have XeLaTeX or LuaLaTeX and no experience with them.

  • You mention you use a Mac-based system. Do you have MacTeX installed? If so, you should have both XeLaTeX and LuaLaTeX at the ready.

    The problem is not related with bibliography: Make a simple "Hello" document and paste this: ′ or this: − and you will see the same problem. You can solve the problem replacing this characters with \'{} and $-$ , or as commented, using xelated or lualatex (that most probably are already installed in your computer).
