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 ISO8859-5, a Cyrillic
character set with which you can type Bulgarian, Belarusian,
Macedonian, Russian, Serbian, and Ukrainian. Note that the charset
KOI8-R is preferred in Russia.
