124 | the use of advanced wide-character support present in the system

125 | <application>NCurses</application> library. This is needed for

126 | proper display of characters and line wrapping in multibyte locales.</para>

130 | for terminal output from the current locale.
|
---|
131 | A configuration step is still needed (see below), but,
|
---|
132 | unlike the situation without this switch, the configuration step becomes
|
---|
133 | the same for all users (without the switch, one would have to specify the
|
---|
134 | display charcter set explicitly). This is important for environments such
|

135 | as a LiveCD, where the amount of system-specific configuration steps has

136 | to be reduced to the minimum.</para>
