If you use multiple terminal types for one computer it may be better to selectively add the <tt class="envar">GROFF_NO_SGR</tt> environment variable for the terminals that do not support SGR. </p> </div> </div> <p> If the character set of the locale uses 8-bit characters, search for the line beginning with “<span class= "quote">NROFF</span>” in <tt class= "filename">/etc/man.conf</tt>, and verify that it matches the following: </p> <pre class="screen">NROFF /usr/bin/nroff -Tlatin1 -mandoc</pre> <p> Note that “<span class="quote">latin1</span>” should be used even if it is not the character set of the locale. The reason is that, according to the specification, <span><strong class= "command">groff</strong></span> has no means of typesetting characters outside International Organization for Standards (ISO) 8859-1 without some strange escape codes. When formatting man pages, <span><strong class="command">groff</strong></span> thinks that they are in the ISO 8859-1 encoding and this <em class= "parameter"><tt>-Tlatin1</tt></em> switch tells <span><strong class="command">groff</strong></span> to use the same encoding for output. Since <span><strong class= "command">groff</strong></span> does no recoding of input characters, the f ormatted result is really in the same encoding as input, and therefore it is usable as the input for a pager. </p> <p> This does not solve the problem of a non-working <span><strong class="command">man2dvi</strong></span> program for localized man pages in non-ISO 8859-1 locales. Also, it does not work with multibyte character sets. The first problem does not currently have a solution. The second issue is not of concern because the LFS installation does not support multibyte character sets. </p> <p> Additional information with regards to the compression of man and info pages can be found in the BLFS book at <a href= "http://www.linuxfromscratch.org/blfs/view/cvs/postlfs/compressdoc.html"> <i>http://www.linuxfromscratch.org/blfs/view/cvs/postlfs/compressdoc.html</i></a>. </p> </div> <div class="content" lang="en" xml:lang="en"> <div class="titlepage"> <a id="contents-man" name="contents-man"></a> <h2 class="sect2"> 10.41.2.
