108 <para>The <parameter>-I '\033(K'</parameter> option tells
109 <command>agetty</command> to send this escape sequence to the terminal
110 before doing anything else. This escape sequence switches the console
111 character set to a user-defined one, which can be modified by running
112 the <command>setfont</command> program. The <command>console</command>
[fb40919]113 initscript from the CLFS-Bootscripts package calls the
[3f8be484]114 <command>setfont</command> program during system startup. Sending this
115 escape sequence is necessary for people who use non-ISO 8859-1 screen
116 fonts, but it does not affect native English speakers.</para>
