I'm in AUCTeX in a 32-bit Win7 machine. When compiling the master file with pdflatex I'm getting the error msg given below. Can you help me understand the error and correct it?

ERROR: Package inputenc Error: Unicode char \u8:è\itemS not set up for use with LaTeX.

  • I'm afraid AUCTeX can't figure out accented letters (quite common) in Italian such as: à, è, é... it says it is not compatible with utf8 inputenc. How do I fix this for AUCTeX in win7? Oct 8, 2014 at 21:17

    This has nothing to do with AUCTeX. You probably have a wrong file encoding set. The bar between the buffer window and the command minibuffer should have a U at the far left.

  • It looks like è is encoded as a single byte so not utf8 Oct 8, 2014 at 21:20

    Add % -*- coding: utf-8; -*- as first line of your .tex files. Oct 8, 2014 at 22:53

Adding % -*- coding: utf-8; -*- to both the master.tex file and the dependant file worked! I can also see the U at the far left corner of buffer separation bar, but I can't remember whether it wasn't there yesterday. Thank you, folks for your help.
