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