+  <para>Filesystems with MS-DOS or Windows origin (i.e.: vfat, ntfs, smbfs, cifs,
+  iso9660, udf) need the <quote>iocharset</quote> mount option in order for
+  non-ASCII characters in file names to be interpreted properly. The value
+  of this option should be the same as the character set of your locale,
+  adjusted in such a way that the kernel understands it. This works if the
+  relevant character set definition (found under File systems -&gt;
+  Native Language Support) has been compiled into the kernel
+  or built as a module. The <quote>codepage</quote> option is also needed for
+  vfat and smbfs filesystems. It
+  should be set to the codepage number used under MS-DOS in your country. E.g.,
+  in order to mount USB flash drives, a ru_RU.KOI8-R user would need the
+  following line in <filename>/etc/fstab</filename>:</para>
+
+<screen>/dev/sda1    /media/flash vfat noauto,user,quiet,showexec,iocharset=koi8r,codepage=866 0 0</screen>
+
+  <para>The corresponding line for ru_RU.UTF-8 users is:</para>
+
+<screen>/dev/sda1    /media/flash vfat noauto,user,quiet,showexec,iocharset=utf8,codepage=866 0 0</screen>
+
+  <note><para>In the latter case, the kernel emits the following message:</para>
+
+<screen><computeroutput>FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!</computeroutput></screen>
+
+  <para>This negative recommendation should be ignored, since all other values
+  of the <quote>iocharset</quote> option result in wrong display of filenames in
+  UTF-8 locales.</para></note>
+
+  <para>It is also possible to specify default codepage and iocharset values for
+  some filesystems during kernel configuration. The relevant parameters
+  are named
+  <quote>Default NLS Option</quote> (CONFIG_NLS_DEFAULT),
+  <quote>Default Remote NLS Option</quote> (CONFIG_SMB_NLS_DEFAULT),
+  <quote>Default codepage for FAT</quote> (CONFIG_FAT_DEFAULT_CODEPAGE), and
+  <quote>Default iocharset for FAT</quote> (CONFIG_FAT_DEFAULT_IOCHARSET).
+  There is no way to specify these settings for the
+  ntfs filesystem at kernel compilation time.</para>
