<H2>42.3 An Example</H2>
<A NAME="idx975"><!></A>
<P>An example of when you would want to imbue a new locale on a stream might be the case where a file has a header that requires a different code conversion facet. The following code imbues the JIS to UNICODE conversion facet from <A HREF="40.html">Chapter&nbsp;40</A> onto a stream, reads a single line, then imbues the default locale to continue processing the file:</P>

<UL><PRE>
std::wstring header;
std::wstring body;
typedef std::basic_ifstream&lt;wchar_t,JIS_char_traits&gt; JIS_ifstream;
JIS_fstream in("special.txt");
UnicodeJISConversion&lt;wchar_t,char,JISstate_t&gt; cvtfac;
std::locale cvtloc(std::locale(),&amp;cvtfac);
in.rdbuf()-&gt;pubimbue(cvtloc);
std::getline(in,header);
in.rdbuf()-&gt;pubimbue(std::locale());
in &gt;&gt; body;
</PRE></UL>
