+
+<para>Note that <quote>latin1</quote> should be used even if it is not
+the character set of the locale. The reason is that, according to the
+specification, <command>groff</command> has no means of typesetting
+characters outside International Organization for Standards
+(ISO) 8859-1 without some strange escape codes. When formatting manual
+pages, <command>groff</command> thinks that they are in the ISO 8859-1
+encoding and this <parameter>-Tlatin1</parameter> switch tells
+<command>groff</command> to use the same encoding for output. Since
+<command>groff</command> does no recoding of input characters, the
+formatted result is really in the same encoding as input, and therefore
+it is usable as the input for a pager.</para>
+
+<para>This does not solve the problem of a non-working
+<command>man2dvi</command> program for localized manual 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.</para>
