This is with ref to my previous question Package clash in multilingual report.

\documentclass[11pt,table,a4paper]{article}
\usepackage{lmodern}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{CJKutf8}
\usepackage[english,russian]{babel}

\newenvironment{SChinese}{%
 \CJKfamily{gbsn}%
 \CJKtilde
 \CJKnospace}{}

 \begin{document}
 \selectlanguage{russian}
  Это мой первый многоязычный докладе.
  Инфантильный гипертрофический стеноз привратника - это серьёзное 
 \selectlanguage{english}
  This is my first multilingual report.

 \begin{CJK}{UTF8}{}
  \begin{SChinese}
    这是我的第一个多语种的报告。
  \end{SChinese}
  \end{CJK}

  \end{document}

when I try to compile it, I get following error message.

LaTeX Warning: Unused global option(s):

How can I avoid such error message.

Best Answer

The error you get is due to a "no-break space" character, according to what I can gather by copying an pasting your message.

This character is not usually set up by the [utf8] option and it's invisible to many editors, so it can slip in a document without the typist knowing it.

Solution: add in your preamble

\DeclareUnicodeCharacter{00A0}{ }

if you don't mean to type a no-break space, or

\DeclareUnicodeCharacter{00A0}{~}

if you want that the character stands for what its name says.

UPDATE

Recent (after 2015-01-01) versions of the UTF8 configuration file for inputenc do define U+00A0 as \nobreakspace, so this should be of no concern, now.
