111 <para>The <parameter>-I '\033(K'</parameter> option tells
112 <command>agetty</command> to send this escape sequence to the terminal
113 before doing anything else. This escape sequence switches the console
114 character set to a user-defined one, which can be modified by running
115 the <command>setfont</command> program. The <command>console</command>
116 initscript from the CLFS-Bootscripts package calls the
117 <command>setfont</command> program during system startup. Sending this
118 escape sequence is necessary for people who use non-ISO 8859-1 screen
119 fonts, but it does not affect native English speakers.</para>
