NLS UTF-8

modulename: nls_utf8.ko

configname: CONFIG_NLS_UTF8

Linux Kernel Configuration
└─>File systems
└─>Native Language Support
└─>NLS UTF-8
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you want to display filenames with native language characters
from the Microsoft FAT file system family or from JOLIET CD-ROMs
correctly on the screen, you need to include the appropriate
input/output character sets. Say Y here for the UTF-8 encoding of
the Unicode/ISO9646 universal character set.
