<refsection><info><title>Description</title></info>

<para>If the value of the <parameter>man.charmap.enabled</parameter>
parameter is non-zero, a "character map" is used to substitute certain
Unicode symbols and special characters with appropriate roff/groff
equivalents, just before writing each man-page file to the
filesystem. If instead the value of
<parameter>man.charmap.enabled</parameter> is zero, Unicode characters
are passed through "as is".</para>

<refsection><info><title>Details</title></info>

<para>For converting certain Unicode symbols and special characters in
UTF-8 or UTF-16 encoded XML source to appropriate groff/roff
equivalents in man-page output, the DocBook XSL Stylesheets
distribution includes a <link xlink:href="http://docbook.sourceforge.net/snapshot/xsl/manpages/charmap.groff.xsl">roff character map</link> that is compliant with the <link xlink:href="http://www.w3.org/TR/xslt20/#character-maps">XSLT character
map</link> format as detailed in the XSLT 2.0 specification. The map
contains more than 800 character mappings and can be considered the
standard roff character map for the distribution.</para>

<para>You can use the <parameter>man.charmap.uri</parameter>
parameter to specify a URI for the location for an alternate roff
character map to use in place of the standard roff character map
provided in the distribution.</para>

<para>You can also use a subset of a character map. For details,
see the <parameter>man.charmap.use.subset</parameter>,
<parameter>man.charmap.subset.profile</parameter>, and
<parameter>man.charmap.subset.profile.english</parameter>
parameters.</para>
