<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 in the options portion of its
mount line in <filename>/etc/fstab</filename>:</para>
<para>Filesystems with MS-DOS or Windows origin (i.e. vfat, ntfs, smbfs,
cifs, iso9660, udf) need a special option, utf8, in order for non-ASCII
characters in file names to be interpreted properly. For non-UTF-8 locales,
the value of <option>iocharset</option> should be set to be the same as the
character set of the 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 when configuring the kernel)
has been compiled into the kernel or built as a module. However, if the
character set of the locale is UTF-8, the corresponding option
<option>iocharset=utf8</option> would make the file system case sensitive. To
fix this, use the special option <option>utf8</option> instead of
<option>iocharset=utf8</option>, for UTF-8 locales. 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.
For example, in order to mount USB flash drives, a ru_RU.KOI8-R user would
need the following in the options portion of its mount line in
<filename>/etc/fstab</filename>:</para>
<screen><literal>noauto,user,quiet,showexec,iocharset=koi8r,codepage=866</literal></screen>
<screen><literal>noauto,user,quiet,showexec,codepage=866,iocharset=koi8r</literal></screen>
<para>The corresponding options fragment for ru_RU.UTF-8 users is:</para>
<screen><literal>noauto,user,quiet,showexec,iocharset=utf8,codepage=866</literal></screen>
<screen><literal>noauto,user,quiet,showexec,codepage=866,utf8</literal></screen>
<note>
<para>Note that using <option>iocharset</option> is the default for
<literal>iso8859-1</literal> (which keeps the file system case
insensitive), and the <option>utf8</option> option tells
the kernel to convert the file names using UTF-8 so they can be
interpreted in the UTF-8 locale.</para>
<!--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,
@ -84,7 +95,7 @@ EOF</userinput></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>

some filesystems during kernel configuration. The relevant parameters
