# Package inputenc Error: Unicode char â„¡ (U+2121)(inputenc) not set up for use with LaTeX. \printbibliography[heading=bibintoc] [closed]

I have some problem with the "Package inputenc Error: Unicode char â„¡ (U+2121)(inputenc)". I am using Zotero and "export" the bibliography to a bib file. To correct certain information I recently used jabref. I don't know if this could have any influence. The preamble of the document:

``````\documentclass {report}

\usepackage[utf8]{inputenc}

\DeclareUnicodeCharacter{B0}{\textdegree}

\usepackage[T1]{fontenc}

\usepackage{textcomp}

\usepackage{amsmath}

\usepackage{amssymb}

\usepackage{longtable}

\usepackage{rotating}

\usepackage{todonotes}

\usepackage{enumerate}

\usepackage[hyphenbreaks]{breakurl}

\usepackage[backend=biber, citestyle=authoryear,sorting=nyt,natbib=true,ibidtracker=true]{biblatex}
• If it is you can add `\DeclareUnicodeCharacter{2121}{\textsc{Tel}}` to your preamble. – David Carlisle Jul 20 '17 at 21:07
• U+2121 TELEPHONE SIGN (℡) in UTF-8 is three bytes `E2 84 A1`, so that's in your file. What you've pasted in the question are three characters `â` then `„` then `¡`. So at least your terminal that displayed the output(?) must be using an encoding in which 84 denotes `„` and according to this table that's WINDOWS-1252. Whatever it is, there's some mismatch between the encoding specified (`utf8`) and the one actually used. You need to post your `test.bib` to help answer the question. – ShreevatsaR Jul 20 '17 at 21:07
• Does your `.bib` file contain any accents as macros e.g. `\'e` or whatever? If so, try replacing them with their unicode equivalents e.g. `é` and make sure that your `.bib` uses UTF8 encoding, as well as your `.tex` file. Biber/Biblatex does not cope gracefully with traditional LaTeX ways of doing accents and often generates strange warnings about unknown unicode character in response. Feeding it actual unicode characters makes it happy. – cfr Jul 21 '17 at 0:24
