No matter how I try to do it I always get the following error :
! Package inputenc Error: Unicode char \u8: not set up for use with LaTeX.
I have tried using $^{\circ}$
, \deg
, \textdegree
, pasting the ° symbol directly, to no avail.
Here is the header of my document, in case one of those could be causing the errors :
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage[francais]{babel}
%\FrenchItemizeSpacingfalse
\frenchbsetup{CompactItemize=false}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amsthm}

If you're getting literally that error—with no visible character after the
\u8:
—then what's probably happening is that you have some sort of invisible or space unicode character in your document. For instance, on my Mac, if I hit option-space, I get a non-breaking space, which gives an error that looks like that. You also might have some other character; a zero-width breakable space, for instance. If you copied and pasted your error, looking at the source of this page indicates that you might have a soft hyphen in your source (Unicode character0xAD
, representing a valid hyphenation point but not typeset unless there's a word-break). Thus, find the line it's occurring on, and comb through that line until you find it. Retype it if necessary, but a good editor should let you find it. Once you delete it, then your first three methods should work.When I use your header (commenting out
\frechbsetup
, which doesn't seem to exist, and using\documentclass{article}
),$^{\circ}$
renders as a largeish circle in the superscript position,$\deg$
renders as the upright text "deg", and\textdegree
renders as a smaller circle. A literal°
doesn't work by default. To make it work, you can use\DeclareUnicodeCharacter{B0}{\textdegree}
. This tellsinputenc
to treat the Unicode character0xB0
, the°
, as though it were\textdegree
, which is what you want. You could also use this to see if your problem is the soft hyphen; insert\DeclareUnicodeCharacter{AD}{\Huge [ICI]}
to get the text[ICI]
rendered into your document in huge letters wherever there's a soft hyphen. (Of course, if there's some other invisible character, you'll just get the error.)Also, although I've never used it, you could try using XeLaTeX instead of PDFLaTeX; it has full UTF-8 support out of the box.
