Sorry if this is an already answered question, but I searched for hours through the Internet without success.

It seems like the packages used in my main.tex file do not affect my .bib file, in fact I get errors like

undefined inputenc `utf8` character encoding 

while in the main file I use succesfully the \usepackage[utf8]{inputenc}.

Moreover, I saw that even comments don't work inside the bibliography.

Is there something I'm missing?

Sorry but I'm pretty new to LaTeX and thanks in advance for your time!

EDIT:

These are the packages concerning language and encoding settings included in the main file:

% Language and encoding
\documentclass[a4paper, oneside, 12pt, english, italian]{report}
\usepackage[T1]{fontenc}    
\usepackage[utf8]{inputenc} 
\usepackage[english,italian]{babel} 

% Bibliography
\usepackage[autostyle,italian=guillemets]{csquotes}
\usepackage[backend=biber]{biblatex}
\addbibresource{bibliografia.bib}

If it could be of any help, this is my bibliography:

I don't know where the errors are precisely, because I always get them at the \end{document} element in the main file.

The two errors are: 1. Undefined control sequence. \end 2. Package inputenc Error: Keyboard character used is undefined(inputenc) in inputencoding 'utf8'. \end

    bibtex or biblatex + biber? bibtex does not support UTF8. – Schweinebacke Feb 10 '17 at 8:48
  • Normally biblatex picks up the document encoding and assumes that the .bib file has the same encoding (you can explicitly override that, if need be). But not all characters are set up in inputenc, sometimes weird unicode symbols like non-breaking spaces confuse TeX. We would need to see an MWE (please explicitly state the encoding of your files). – moewe Feb 10 '17 at 12:29
  • Thanks for your answers. @Schweinebacke: I'm using biblatex + biber – Solaire Feb 10 '17 at 13:23

    LaTeX does not know a command . Maybe this should be © (without backslash in front) or even , with slash as a kind of separator. Unfortunately your code is still not an MWE. – Schweinebacke Feb 10 '17 at 13:45

The copyright symbols are the problem. Replace them with \textcopyright{} and all is fine:

@online{headspace:appleStore,
    title        = {Headspace: Guided Meditation and Mindfulness sull'App Store},
    date         = {2016},
    organization = {Headspace meditation limited \textcopyright{} Headspace Inc},
    url          = {https://itunes.apple.com/it/app/headspace-guided-meditation/id493145008?mt=8}
}

@online{headspace:playStore,
    title        = {Headspace - meditation - App Android su Google Play},
    date         = {2016},
    organization = {Headspace meditation limited \textcopyright{} Headspace Inc},
    url          = {https://play.google.com/store/apps/details?id=com.getsomeheadspace.android&hl=it}
}

Or even just ©, without the backslash:

@online{headspace:appleStore,
    title        = {Headspace: Guided Meditation and Mindfulness sull'App Store},
    date         = {2016},
    organization = {Headspace meditation limited © Headspace Inc},
    url          = {https://itunes.apple.com/it/app/headspace-guided-meditation/id493145008?mt=8}
}

@online{headspace:playStore,
    title        = {Headspace - meditation - App Android su Google Play},
    date         = {2016},
    organization = {Headspace meditation limited © Headspace Inc},
    url          = {https://play.google.com/store/apps/details?id=com.getsomeheadspace.android&hl=it}
}
