I'm currently writing my final thesis in TeXstudio and for a better organization I'm writing each chapter in a different text file. I'm also writing in Spanish and as far as I know, the inputenc package with utf8 configuration (\usepackage[utf8]{inputenc}) along the babel package (\usepackage[spanish,activeacute]{babel}) must be ok for that. I started to write the first chapter with Spanish accents without any problem, nevertheless as soon as I started writing chapter 2 there was an inputenc error whenever I typed an accented word or the letter ñ. The error is like this:

Package inputenc Error: Unicode char \u8: étr not set up for use with LaTeX
Package inputenc Error: Unicode char \u8: ño not set up for use with LaTeX
Package inputenc Error: Unicode char \u8: ón not set up for use with LaTeX
Package inputenc Error: Unicode char \u8: És not set up for use with LaTeX

I don't really get it since I wrote chapter 1 without problems. I'm using those lines to add the chapters to the main file.


It's as if TeXtstudio wouldn't keep recognizing the inputenc function after the first \input{file.tex} or something. And the wiered thing is that the inputenc error is for the accented words interacting inside a word, for example étr or ño inside the words paramétrico and diseño.

I can only make it work if I place the whole chapter's 2 content into the chapter's 1 TeX file.

Any ideas?

  • you say the problem disappears when you copy Capitulo2.tex's content into Capitulo1.tex. What happens when you create a copy of Capitulo1.tex, rename it to Capitulo2a (or whatever) and copy Capitulo2's content into that file?

  • Your second file is not utf8 encoded. See also tex.stackexchange.com/questions/105672/… Mar 29, 2013 at 11:12
  • Brilliant! just as you said my second file was not UTF-8 encoded! It was ANSI encoded and I don't know why since I created the whole files at once. However, in order to show the answer to this problem, what I done was to check the tex file codification within notepad, then I realized that some of my files as Capitulo1 and the main file were in UTF-8, but some others as Capitulo2 were ANSI coded, so I just opened them, saved them with the same name but with UTF-8 codification, then reopened them in Textstudio and the problem was solved! Thanks again! Mar 29, 2013 at 23:13
  • Although Nils L's method would have also worked since Capitulo1.tex was UTF-8 coded. Mar 29, 2013 at 23:18

Try using:


If it doesn't work, then try (For iso-8859-1):


Write in normal spanish, don't worry about special characters (i.e. use "diseño", you don't have to write "dise\~no").

This should work just fine. It does for me.
