I am having trouble putting a raised registered symbol (\textsuperscript{\textregistered}) in my biblatex bibliography.


\usepackage[backend=biber, bibencoding=utf8, style=authoryear-icomp]{biblatex}





And the reference:

title = {Title\textsuperscript{\textregistered}},
author = {Some Guy},
year = {2014},

This produces the following errors:

./test.tex:11: Argument of \UTFviii@two@octets has an extra }.

./test.tex:11: Paragraph ended before \UTFviii@two@octets was complete.

./test.tex:11: Package inputenc Error: Keyboard character used is undefined

and the bibliography entry shows up without the symbol.

Using either the \textsuperscript or \textregistered alone does not produce this problem. Any suggestions?

  • Welcome to TeX.SX! I get no error; can you tell what TeX distribution you're using? – egreg Nov 24 '14 at 16:15
  • Thanks. I am using TeX Live 2013 on OSX Yosemite, all up to date. – lydhvin Nov 24 '14 at 20:58
  • TeX Live is 2014 now. – egreg Nov 24 '14 at 20:59
  • Is it 2014 already?;) I'll upgrade and give it a shot. But I'm pretty sure I had the same problem last year, but I just gave up. – lydhvin Nov 24 '14 at 21:18
  • It has been 2014 for several months (from beginning of July). – egreg Nov 24 '14 at 21:21

The error is caused by an outdated version of biblatex and biber.

An update to TeX Live 2014 (on Mac OS X it's MacTeX 2014) should solve the issue.

  • How can this be solved with something online, like ShareLaTeX or Overleaf? – Adam_G Mar 13 '17 at 16:50
  • @Adam_G Sorry; if they don't upgrade their software… – egreg Mar 13 '17 at 17:08
