72 | adding the <parameter>-c</parameter> option to the <envar>NROFF</envar>
|

73 | variable. If you use multiple terminal types for one computer it may be better

75 | terminals that do not support SGR.</para></note>

77 | <para>If the character set of the locale uses 8-bit characters, search for the

---|
78 | line beginning with <quote>NROFF</quote> in <filename>/etc/man.conf</filename>,
|
---|
79 | and verify that it matches the following:</para>
|

80 |
|
---|
81 | <screen>NROFF /usr/bin/nroff -Tlatin1 -mandoc</screen>
|
---|
82 |
|
---|
83 | <beginpage/>
|
---|
84 |
|
---|
85 | <para>Note that <quote>latin1</quote> should be used even if it is not
|
---|
86 | the character set of the locale. The reason is that, according to the
|
---|
87 | specification, <command>groff</command> has no means of typesetting
|
---|
88 | characters outside International Organization for Standards
|
---|
89 | (ISO) 8859-1 without some strange escape codes. When formatting man
|
---|
90 | pages, <command>groff</command> thinks that they are in the ISO 8859-1
|
---|
91 | encoding and this <parameter>-Tlatin1</parameter> switch tells
|
---|
92 | <command>groff</command> to use the same encoding for output. Since
|
---|
93 | <command>groff</command> does no recoding of input characters, the
|
---|
94 | formatted result is really in the same encoding as input, and therefore
|
---|
95 | it is usable as the input for a pager.</para>
|
---|
96 |
|
---|
97 | <para>This does not solve the problem of a non-working
|
---|
98 | <command>man2dvi</command> program for localized man pages in
|
---|
99 | non-ISO 8859-1 locales. Also, it does not work with multibyte
|
---|
100 | character sets. The first problem does not currently have a solution.
|
---|
101 | The second issue is not of concern because the LFS installation does
|
---|
102 | not support multibyte character sets.</para>
